Emotron AB 01-3990-11r3
1. Motor load too great or VSD
capacity too small
2. Motor parameter error
(vector mode)
3. The gain is too great during vec-
tor mode operation
4. The current detect circuit is
faulty
Cause
1. Detection circuit malfunc-
tion
2. Bad connection for CT signal
cable
1. Heavy load
2. Inappropriate settings of 0-
02, 9-08~11
Heavy load
1. Heavy load
2. Insufficient settings of 9-14,
9-15
1. Power voltage too low
2. Power voltage varies widely
1. Heavy load
2. Ambient temperature too
high or bad ventilation
1. Increase acceleration /
Deceleration time (3-02/3-03)
2. Input correct motor Parame-
ter
3. Change stator Resistance
gain
and Rotator resistance gain
(14-0/14-1). Recommended
decrease 50~100, until 0
4. Send back to Emotron
1. Check the noise between
power line and motor line
2.Send the VSD back to be
repaired
1. Increase the motor capacity
2. Set 0-02, 9-08~11 properly
Increase the VSD capacity
1. Increase the VSD capacity
2. Set 9-14, 9-15 properly
1. Improve power quality or
increase the value of 2-01
2. Set a longer acceleration time
3. Increase VSD capacitor
4. Add a reactor at the power
input side
1. Check if there are any prob-
lems with the load
2. Increase VSD capacity
3. Improve ventilation conditions
