Symptom Possible cause Test Solution
Motor not run-
ning Service switch open or miss-
ing motor connection. – Connect the motor and check the serv-
ice switch.
No mains power with 24 V DC
option card. – Apply mains power.
LCP stop. – Depending on the operating mode,
press [Auto On] or [Hand On].
Missing start signal (Standby). – Apply a valid start signal.
Motor coast signal active
(Coasting). – Apply 24 V on terminal 27 or program
this terminal to
[0] 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 param-
eter 3-13 Reference Site . Set preset refer-
ence active in parameter group 3-1* Ref-
erences . Check for correct wiring. Check
scaling of terminals. Check reference
signal.
Motor running
in wrong direc-
tion Motor rotation limit. Check that parameter 4-10 Motor
Speed Direction is programmed
correctly.
Program correct settings.
Active reversing signal. Check if a reversing command is
programmed for the terminal in
parameter group 5-1* Digital inputs .
Deactivate reversing signal.
Wrong motor phase connec-
tion. – Correct motor phase connection, or set
parameter 1-06 Clockwise Direction to [1]
Inverse .
Motor is not
reaching maxi-
mum speed Frequency limits set wrong. Check output limits in parameter
4-13 Motor Speed High Limit [RPM] ,
parameter 4-14 Motor Speed High
Limit [Hz]
, and parameter 4-19 Max
Output Frequency .
Program correct limits.
Reference input signal not
scaled correctly. Check reference input signal scal-
ing in
parameter group 6-0* Analog
I/O mode and parameter group 3-1*
References .
Program correct settings.
Motor speed
unstable Possible incorrect parameter
settings. Check the settings of all motor pa-
rameters, including all motor com-
pensation settings. For closed-loop
operation, check PID settings. Check settings in parameter group 1-6*
Load Depen. Setting . For closed-loop
operation, check settings in parameter
group 20-0* Feedback .
Motor runs
rough Possible overmagnetization. Check for incorrect motor settings
in all motor parameters. Check motor settings in parameter
groups 1-2* Motor data , 1-3* Adv Motor
Data , and 1-5* Load Indep. Setting .
Motor does not
brake Possible incorrect settings in
the brake parameters. Ramp-
down times may be too short. Check brake parameters. Check
ramp time settings. Check parameter groups 2-0* DC Brake
and 3-0* Reference Limits .
