Cause
Remedy
Motor does not
rotate
DC-bus voltage is too low
• Red LED is blinking every 1 s
• Display in the keypad:
LU
Check mains voltage
Controller is inhibited
• Green LED is blinking
• Display in the keypad:
Deactivate controller inhibit
• Note: Controller inhibit can be set via
several sources !
•
C00158
displays all active sources for
controller inhibit.
Automatic start is inhibited
(Bit 0 in
C00142
= 1)
LOW/HIGH edge at RFR
If required, correct starting condition with
C00142
DC-injection braking (DCB) is active
Deactivate DC injection brake
Mechanical motor brake is not released
Release mechanical motor brake manually or
electrically
Quick stop (QSP) is active
• Display in the keypad:
Deactivate quick stop
• Note: Quick stop can be set via several
sources!
•
C00159
displays all active sources of quick
stop.

device
command
Assignment of several mutually exclusive
functions with a signal source in
C00701
Correct configuration in
C00701
Motor rotates
irregularly
Motor cable is defective
Check motor cable
Maximum motor current in motor or
generator mode is set too low
Adjust settings to the application:
C00022:
Imax in motor mode
C00023
: Imax in generator mode
Motor is underexcited or overexcited
Check parameterisation:
C00006
: Motor control
C00015
: VFC: V/f base frequency
C00016
: VFC: Vmin boost
Rated motor data (stator resistance, speed,
current, frequency, voltage) and cos
ϕ
and/or magnetising inductance is not
adapted to the motor data
