5.2.2 Amplifier Malfunctions
Amplifier Malfunctions
Possible Causes: Solution
─ When the motor is turning
in the clockwise direction
(observe the motor shaft)
I-FPOS is reduced
─ Resolver does not func-
tion correctly
─ Resolver connected
incorrectly
─ Check Resolver
─ Connect Resolver according to
schematic (Page22)
─
Motor does not turn
─
Motor current reaches
limit, however, without
torque
─ Resolver does not func-
tion correctly
─ Resolver connected
incorrectly
─ Check connections on motor
terminal board
U, V, W
─
The Motor "spins
through"
─ The torque is too low or
different in the directions
─ Resolver does not func-
tion correctly
─ Resolver connected
incorrectly
─ Check the
M-ROFF parameter
─ Check the motor and feedback
connection
─
Motor stops in specified
positions
─ Resolver does not func-
tion correctly
─ Resolver connected
incorrectly
─ Check the
M-POL and M-RPOL
parameters corresponding to the
motor data.
─ Exchange the motor ca-
ble(especially with drag chains)
─ Check motor cable connections
─
The motor oscillates
─ Resolver does not func-
tion correctly
─ Resolver connected
incorrectly
─ Reduce V-KP and/or P-KV
─ Check the feedback cable and
exchange it if needed. (Especial-
ly with drag chains)
