for correct setting for terminal 18
(use default setting).
Apply a valid start signal to start
the motor.

(Coasting)
Check if a coast inv command is
programmed for the terminal in
parameter group E-0# Digital
Inputs
Apply 24 V on terminal or program
this terminal to
No operation.
Wrong reference signal source
Check reference signal: Local,
remote or bus reference? Preset
reference active? Terminal
connection correct? Scaling of
terminals correct? Reference signal
available?
Program correct settings. Check
F-02 Operation Method
. Set preset
reference active in parameter
C-05 Multi-step Frequency 1 - 8
.
Check for correct wiring. Check
scaling of terminals. Check
reference signal.
Motor running in wrong
direction
Motor rotation limit
Check that
H-08 Reverse Lock
is
programmed correctly.
Program correct settings.
Active reversing signal
Check if a reversing command is
programmed for the terminal in
parameter group
E-0# Digital inputs.
Deactivate reversing signal.
Wrong motor phase connection
See
3.5 Check Motor Rotation
in this
manual.
Motor is not reaching
maximum speed
Frequency limits set wrong
Check output limits in
F-17 Motor
Speed High Limit [RPM]
,
F-15 Motor
Speed High Limit [Hz]
and
F-03 Max
Output Frequency 1
Program correct limits.
Reference input signal not scaled
correctly
Check reference input signal
scaling in AN-## Reference limits in
parameter group F-5#.
Program correct settings.
Motor speed unstable
Possible incorrect parameter
settings
Check the settings of all motor
parameters, including all motor
compensation settings. For closed-
loop operation, check PID settings.
Check settings in parameter group
AN-##. For closed-loop operation,
check settings in parameter group
CL-0#
Motor runs rough
Possible over-magnetization
Check for incorrect motor settings
in all motor parameters.
Check motor settings in parameter
groups P-0#
