speed operation. If the motor response is slow, try
increasing the value at Cn.51 in 5%
increments (or, try increasing the value at
Cn.45 in 100% increments).
“OC1” fault or jerking occurs
during a high speed operation. Cn.41 PM SpdEst Kp
Cn.42 PM SpdEst Ki
Try increasing the value at Cn. 41 in
increments of 10 and the value at Cn.42
in increments of 1.
Note that a fault may occur if the values
at Cn. 41 and Cn.42 are set too high.
Jerking occurs during a low speed
operation.
Cn.13 ASR I Gain 1
Try increasing the value at Cn.13 (low
speed range speed controller I gain) to
eliminate jerking.
A “clanking” noise is heard at the
beginning of startup or during
deceleration.
Cn.12 ASR P Gain 1
Cn.13 ASR I Gain 1
Cn.40 PMdeadVolt
Per Try increasing the values at Cn.12 and
Cn.13 in 10% increments, or try
decreasing the value at Cn.40 in 10%
decrements.
The motor cannot reach the
speed reference when it is
operated at or above the rated
speed, or when the acceleration
is not responsive.
Cn.50 V Con HR
Cn.51 V Con Ki
Try increasing the value at Cn.50 in 1%
increments if the motor cannot reach the
speed reference.
Try increasing the value at Cn.51 in 10%
increments if the motor acceleration is
not responsive.
“OC1” trip occurs after an abrupt
regenerative load (over 100%).
Cn.12 ASR P Gain 1
Cn.13 ASR I Gain 1 Try decreasing the values at Cn.12 and
Cn.13 in 10% decrements.
The motor jerks during
acceleration.
Cn.42 PM SpdEst Ki
Try increasing the speed estimator
proportional gain at Cn.42 in increments
of 5.
A major current rise occurs when
the motor is stopped during a
20:1 speed startup.
Cn.13 ASR I Gain 1
Try increasing the value at Cn. 13 in 10%
increments.
An oscillation occurs when an
abrupt load is applied to the
motor during a low speed
operation.
Cn.41 PM SpdEst Kp
Cn.42 PM SpdEst Ki Try increasing the values at Cn. 41 and
Cn.42 in 10% increments.
During a PM speed search, the
speed search stops at around
20% of the base frequency, and
the motor is stopped and starts
again after a major current rise.
Cn.69 SS Pulse Curr
Try decreasing the value at Cn.69 in 5%
decrements.
During a high-speed operation in
PM control mode utilizing the
Cn.78 KEB Start Lev
Cn.79 KEB Stop Lev Try increasing the values at Cn.78 and
Cn.79 in 5% increments, or try doubling
