- With the Drive disabled turn the motor clockwise (viewed from the front of the
shaft). The value indicated must be positive.
- If the indicated value does not change or random values are shown, check the
power supply and the cabling of the encoder.
- If the indicated value is negative, reverse the encoder connections. Exchange
channel A+ and A- or B+ and B-
Undervoltage Mains voltage parameter incorrectly set (poss. 460 V set, although the device is run
on 400 V). Remedy: set parameter correctly and then acknowledge the failure via
RESET*.
The incoming voltage to the power section of the device is too low due to:
- too low an AC input voltage or long voltage dips
- poor cable connections (e.g. terminals on contactor, choke, filter ... not prop-
erly fixed). Remedy: check connections.
* To RESET the alarms press [Escape] ([Shift] + [Left arrow]). If Enable and Start commands are
configured from teminals (CONFIGURATION / Main.=Terminal), to RESET remove from these terminals
the +24V potential.
NOTE: The RESET alarm operation can be also configured on a digital input (properly
configured).
Other faults
FAILURE POSSIBLE CAUSES
Motor not turning Failure alarm is displayed: see above
Once the error has been corrected enter the failure Reset command
Keypad display is dark: AC voltage supply to terminals U1/V1/W1 missing or
internal fuse faulty
Enable and/or start command missing (Check configuration of the reg. terminals)
Drive not accepting commands: incorrect or wrongly selected operating mode
Protective device of the power supply has tripped: protective device incorrectly
sized or input jumper faulty.
The analog input used for the reference value was not assigned or assigned
differently.
Motor turning in the wrong direction
Polarity of the reference value signal incorrect
Motor incorrectly connected. CAUTION: if the motor lets itself be controlled in
the wrong direction the two encoder cables (A+ and A- or B+ and B-) have to be
changed around in addition to the two lines of the motor cable
Motor not reaching nominal speed
Drive is within speed limitation. Remedy: check Speed max amount, Speed max
pos and Speed max neg parameters
Drive working at current limit (LED Ilimit) Possible causes:
- Motor overloaded
- Inverter sized too small
- Incorrect V/f characteristics set
