6. Locked-rotor
occurs due to
mechanical factors,
resulting in very
heavy load during
running.
Check the running reference and
motor speed (200B-01h) through
Inovance servo commissioning
software or keypad:
Running reference in position control:
200B-0Eh
(Input position reference counter)
Running reference in speed mode:
200B-02h
(Speed reference)
Running reference in torque mode:
200B-03h
(Internal torque reference)
Check that the running reference
is not 0 or very large but the motor
speed is 0 in corresponding mode.
Eliminate mechanical factors.
7. The servo drive
is faulty.
Power off and on the servo drive.
Replace the servo drive if the fault
persists after the servo drive is
powered on again.
E1.941: Parameter modication taking effect only after the servo drive is powered on again
Cause:
After parameters with the effective condition "power-on again" are modied, the servo drive
prompts the user to power on again.
Probable Cause Conrming Method Corrective Action
Parameters with the effective
condition "power-on again"
are modied.
Check whether such parameters
are modied.
Power on the servo drive
again.
E1.942: Parameter storage too frequent
Cause:
The number of function codes that are modied at the same time exceeds 200.
Probable Cause Conrming Method Corrective Action
A great number of function
code parameters are
modied and stored
frequently to EEPROM
(200E-02h = 1)
Check whether the host
controller performs frequent and
fast function code parameter
modication on the servo drive.
Check the running mode.
For parameters that need
not be stored in EEPROM,
set 200E-02h to 0 before
the wiring operation of the
host computer.
