Maloperation of the drive
Maloperation
Cause
Remedy
Motor does not
rotate
DC-bus voltage is too low
• Red LED is blinking every 1 s
Check mains voltage
Controller is inhibited
• Green LED is blinking
Deactivate controller inhibit
• Note: Controller inhibit can be set via
several sources !
•
displays all active sources for
controller inhibit.
Automatic start is inhibited
LOW/HIGH edge at RFR
If required, correct auto-start option in
Auto-start option "Inhibit at power-on"
DC-injection braking (DCB) is active
Deactivate
Mechanical motor brake is not released
Release mechanical motor brake manually or
electrically
Quick stop (QSP) is active
Deactivate quick stop
• Note: Quick stop can be set via several
sources!
• In
, all active sources for quick stop
are displayed.
Setpoint = 0
Select setpoint
Setpoint = 0 with activated fixed setpoint
Set fixed setpoint in
Trouble is active
Clear fault
= 4 "SLVC: Vector control" has
been set, but no motor parameter
identification has been carried out.
Carry out automatic motor parameter
identification with the
controller
command
Automatic motor data identification
Assignment of several mutually exclusive
functions with a signal source in
Correct configuration in
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:
Imax in motor mode
: Imax in generator mode
Motor is underexcited or overexcited
Check parameterisation:
: Motor control
: VFC: V/f base frequency
: 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
Carry out automatic motor parameter
identification with the
controller
command
- or -
Adjust motor parameters manually:
: Motor stator resistance
: Rated motor speed
: Rated motor current
: Rated motor frequency
: Rated motor voltage
: Motor cosine phi
: Motor magnetising inductance
Motor windings are wired incorrectly
Reverse from star connection to delta
connection
