Delta Electronics Network Card VFD XXXM User Manual

Preface  
Thank you for choosing DELTA’s high-performance VFD-M Series. The VFD-M Series is  
manufactured with high-quality components and materials and incorporates the latest microprocessor  
technology available.  
Getting Started  
This quick start will be helpful in the installation and parameter setting of the AC motor drives. To  
guarantee safe operation of the equipment, read the following safety guidelines before  
connecting power to the AC motor drives. For detail information, refer to the VFD-M User Manual  
on the CD supplied with the drive.  
DANGER!  
1.  
2.  
AC input power must be disconnected before any wiring to the AC motor drive is made.  
A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power  
has been turned off. To prevent personal injury, please ensure that power has turned off before  
opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage  
levels.  
3.  
4.  
Never reassemble internal components or wiring.  
The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the  
input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and  
W/T3 directly to the AC mains circuit power supply.  
5.  
6.  
7.  
Ground the VFD-M using the ground terminal. The grounding method must comply with the laws  
of the country where the AC motor drive is to be installed. Refer to the Basic Wiring Diagram.  
VFD-M series is used only to control variable speed of 3-phase induction motors, NOT for 1-  
phase motors or other purpose.  
VFD-M series shall NOT be used for life support equipment or any life safety situation.  
WARNING!  
1.  
2.  
DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive  
easily damage by high-pressure.  
There are highly sensitive MOS components on the printed circuit boards. These components  
are especially sensitive to static electricity. To prevent damage to these components, do not  
touch these components or the circuit boards with metal objects or your bare hands.  
3.  
Only quality person is allowed to install, wire and maintain AC motor drive.  
CAUTION!  
1.  
2.  
Some parameters settings can cause the motor to run immediately after applying power.  
DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight,  
high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic  
particles.  
3.  
4.  
5.  
Only use AC motor drives within specification. Failure to comply may result in fire, explosion or  
electric shock.  
To prevent personal injury, please keep children and unqualified people away from the  
equipment.  
When the motor cable between AC motor drive and motor is too long, the layer insulation of the  
motor may be damaged. Please use a frequency inverter duty motor or add an AC output  
reactor to prevent damage to the motor. Refer to appendix B Reactor for details.  
6.  
The rated voltage for AC motor drive must be 240V for 230V models (120V for 115V models,  
480V for 460V models, 600V for 575V models) and the mains supply current capacity must  
be 5000A RMS (10000A RMS for the 40hp (30kW) models).

Corrective Actions  
Name  
1. Check whether the motors horsepower corresponds to the  
AC drive output power.  
2. Check the wiring connections between the AC drive and  
motor for possible short circuits.  
Over current  
3. Increase the Acceleration time (Pr.10, Pr.12).  
4. Check for possible excessive loading conditions at the motor.  
5. If there are any abnormal conditions when operating the AC  
drive after short-circuit being removed, it should be sent back  
to manufacturer.  
Abnormal increase  
in current.  
1. Check whether the input voltage falls within the rated AC  
drive input voltage.  
2. Check for possible voltage transients.  
3. Bus over-voltage may also be caused by motor regeneration.  
Either increase the decel time or add an optional brake  
resistor.  
Over voltage  
The DC bus voltage  
has exceeded its  
maximum allowable  
value.  
4. Check whether the required braking power is within the  
specified limits.  
1. Ensure that the ambient temperature falls within the specified  
temperature range.  
2. Make sure that the ventilation holes are not obstructed.  
3. Remove any foreign objects from the heatsinks and check for  
possible dirty heat sink fins.  
4. Check the fan and clean it.  
Overheating  
Heat sink  
temperature too  
high  
5. Provide enough spacing for adequate ventilation.  
Low voltage  
1. Check whether the input voltage falls within the AC motor  
drive rated input voltage range.  
2. Check whether the motor has sudden load.  
3. Check for correct wiring of input power to R-S-T (for 3-phase  
models) without phase loss.  
The AC motor drive  
detects that the DC  
bus voltage has  
fallen below its  
minimum value.  
1. Check whether the motor is overloaded.  
2. Reduce torque compensation setting in Pr.54.  
3. Take the next higher power AC motor drive model.  
NOTE: The AC motor drive can withstand up to 150% of the  
rated current for a maximum of 60 seconds.  
Overload  
The AC motor drive  
detects excessive  
drive output current.  
1. Check for possible motor overload.  
2. Check electronic thermal overload setting.  
3. Use a higher power motor.  
4. Reduce the current level so that the drive output current does  
not exceed the value set by the Motor Rated Current Pr.52.  
Overload 1  
Internal electronic  
overload trip  
1. Reduce the motor load.  
2. Adjust the over-torque detection setting to an appropriate  
setting.  
Overload 2  
Motor overload.

Fault  
Name  
Fault Descriptions  
Corrective Actions  
1. Short-circuit at motor output: Check for possible poor  
insulation at the output lines.  
2. Torque boost too high: Decrease the torque compensation  
setting in Pr.54.  
Over-current  
during  
acceleration  
3. Acceleration Time too short: Increase the Acceleration Time.  
4. AC motor drive output power is too small: Replace the AC  
motor drive with the next higher power model.  
1. Short-circuit at motor output: Check for possible poor  
insulation at the output line.  
2. Deceleration Time too short: Increase the Deceleration Time.  
Over-current  
during  
deceleration  
3. AC motor drive output power is too small: Replace the AC  
motor drive with the next higher power model.  
1. Short-circuit at motor output: Check for possible poor  
insulation at the output line.  
2. Sudden increase in motor loading: Check for possible motor  
stall.  
3. AC motor drive output power is too small: Replace the AC  
motor drive with the next higher power model.  
Over-current  
during steady state  
operation  
1. Turn off the power.  
2. Check whether the input voltage falls within the rated AC  
drive input voltage.  
Internal EEPROM  
can not be  
programmed.  
3. Turn on the power.  
1. Check the connections between the main control board and  
the power board  
2. Reset the drive to the factory settings.  
Internal EEPROM  
can not be read.  
1. Input EF (N.O.) on external terminal is closed to GND. Output  
U, V, W will be turned off.  
External Fault  
2. Give RESET command after fault has been cleared.  
1. Check if the motor is suitable for operation by AC motor  
drive.  
2. Check if the regenerative energy is too large.  
3. Load may have changed suddenly.  
Auto accel/decel  
failure  
When (one of) the output terminal(s) is grounded, short circuit  
current is more than 50% of AC motor drive rated current, the AC  
motor drive power module may be damaged.  
NOTE: The short circuit protection is provided for AC motor  
drive protection, not for protection of the user.  
Ground fault  
1. Check whether the IGBT power module is damaged.  
2. Check for possible poor insulation at the output line.  
1. Check the connection between the AC drive and computer  
for loose wires.  
2. Check if the communication protocol is properly set.  
Communication  
error (see Pr.92)  
1. When the external input terminal (B.B) is active, the AC  
motor drive output will be turned off.  
2. Deactivate the external input terminal (B.B) to operate the AC  
motor drive again.
