Code Description
Cn.42 PM SpdEst Ki
Cn.43 PM SpdEst Kp2
Cn.44 PM SpdEst Ki2
speed estimator gains. If a fault occurs or excessive oscillation is
observed at low speeds, decrease the value at Cn.41 in 10%
decrements until the motor operates stably. If ripples occur during
normal operation, increase the value at Cn. 42. The values at Cn.43 and
Cn.44 are used for low speed operations in 200 V motors.
Cn.39 PMdeadBand Per
Cn.40PMdeadVolt Per
Sets the output compensation values . If the motor fails to operate at
low speeds at or below 5% of the rated motor speed, increase the
values set at Cn.39 and Cn.40 by 10% increments. Decrease the values
in 10% decrements if a clanking noise occurs at motor startup and
motor stop.
Cn.45 PM Flux FF %
Sets the high-speed portion of the feed forward rate against the back-
EMF. Feed forwarding enhances operation of the speed estimator.
Increase the value at Cn.45 in 10% increments to suppress motor
oscillation under load. A fault may occur if this value is set too high.
Cn.48 ACR P-Gain
Cn.49 ACR I-Gain
Current Controller P & I Gains . Sets the gain values for the PI current
controller in a synchronous motor. The P gain is the proportional gain
for the current deviation. The current deviation decreases faster with
higher values, as the deviation in voltage output command increases
with increased deviation.
The
I gain is the integral gain for the current deviation. Deviation in
normal operation decreases with higher values.
However, the gain values are limited by the carrier frequency. A fault
may occur due to interference if you set the gain values too high.
Cn.53 Torque Lmt Src
Select a source for torque limit input : Keypad, analog input (V1 and
I2), or input via network communication.
The torque limit value is used to adjust the torque reference size by
limiting the speed controller output. The reverse and regenerative
torque limits may be set for operations in the forward or reverse
direction.
Setting Function
0 KeyPad-1 Sets the torque limit via the
keypad.
1 KeyPad-2
2 V1 Sets the torque limit via the
analog input terminals of the
terminal block.
4 V2
5 I2
6 Int 485 Sets the torque limit via the
communication terminal of
the terminal block.
8 FieldBus Sets the torque limit with the
FieldBus communication
option.
9 UserSeqLink Sets the torque limit with a
user sequence output. The
torque reference is received via
the common area addresses.
