Amplifier Malfunctions
Malfunction of the drive
Possible Causes
Solution
When the motor is turning in the
clockwise direction (observe the
motor shaft), I-FPOS decreases
Resolver not functioning
correctly
Resolver connected incorrectly
Check resolver
Connect the resolver according to the
wiring diagram (see page 42 et seq.)
Motor does not rotate
Motor current has reached limit,
however, without torque
Motor is not connected correctly
Check connections on motor terminal
board
U, V, W
The motor "spins through"
The motor torque is too low or
different in the directions
M-ROFF
is not set to the right
value
Motor and/or feedback is
connected incorrectly
Check the
M-ROFF
parameter
Check the motor and feedback
connection
Motor stops at certain positions
The setting of
M-POL
and/or
M-
RPOL
is incorrect
The motor cable has a wire
break
The motor cable is not
connected to all wires
Check the
M-POL
and
M-RPOL
parameters corresponding to the motor
data.
Replace motor cable (especially for drag
chains)
Check motor cable connections
The motor oscillates
Control gain too high
Shielding of the feedback cable
has a defect
Reduce
V-KP
and/or
P-KV
Check the feedback cable and
exchange it if needed (especially with
drag chains)
