53
CAN
Communication
Fault
• CAN Communication is not
working
• Switch off supply voltage
from all devices that are
connected to CAN bus
• Check CAN-bus wiring and
termination resistor settings
• Check CAN-communication
parameters
C
55
Board Fault
• API3 is not installed or not
working properly
• Switch off supply voltage
• Check API3 supply voltage
• Check API3 wiring
connections
• If problem recurs, replace
inverter
B
56
Generator Current
Limit/Deceleration
Ramp Supervision
• Inverter cannot stop with the
set ramp stretching
• Increase P1.8 Deceleration
Time or P11.1 Ramp
Stretching value
C
57
Motor
Overtemperature
• Motor temperature too high
• Digital input DIA4
deactivated when used for
motor overtemperature
protection
• Wait for motor cooling down
• Avoid running long periods at
low speed
• Check motor temperature
protection wiring
C
58
Overvoltage
Regulator Timeout
• Overvoltage regulator has
been active for 5 sec
C
59
Overvoltage at Start • Too high supply voltage
• Measure supply voltage and
check hoist supply voltage
from hoist type plate
C
60
Power unit fault
• Power unit has stopped
running
• E-stop during running
• Switch off supply voltage
• Check power unit wiring
• If problem recurs, replace
inverter
B
61
Overspeed
• Overspeed situation detected
• Interference in speed signal
connected to ENC1A
• Check supply voltage
• Check load measurement
operation and calibration
• Check sensor cable
grounding and inverter PE-
connections
• Check/replace speed sensor
connected to ENC1A
