PWM Carrier Frequency
Program
Special
Carrier Frequency
This parameter sets the frequency of the pulse width modulation signal applied
to the motor.
Note:
When operating in the
Vector Control
mode the carrier
frequency should be set to 2.2 kHz or above
.
Note:
If the PWM carrier frequency is set at 2.0 kHz or above, it cannot
be decreased below 2.0 kHz while running. If the PWM carrier
frequency is set at 1.9 kHz or below, it cannot be increased above
2.0 kHz while running. Either change requires that the ASD be
stopped and restarted for the changes to take effect.

Retry/Restart
This parameter
Enables/Disables
the ability of the ASD to start into a spinning
motor when the
ST
–
CC
connection opens momentarily and is then closed
(Break/Make ST) or after a power interruption (momentary power failure).
See F312 for more on this parameter setting.
Settings:
0 — Off
1 — Power Failure
2 — Make/Break ST
3 — Make/Break ST or Power Failure

Changeable During Run —
Yes
Regenerative Power Ridethrough Selection
Program
Protection
Under-Voltage/Ridethrough
This parameter determines the motor control response of the ASD in the event
of a momentary power outage, under-voltage condition, or an
selection
(1–3) event.
During a
Ridethrough
, regenerative energy is used to maintain the control
circuitry settings for the duration of the
Ridethrough
; it is not used to drive the
motor. The motor(s) of the system are stopped and then restarted automatically
if so configured.
Note:
If used to restart the motor, the Retry setup of
is required.
Settings:
0 — Off
1 — Ridethrough
2 — Deceleration Stop
Direct Access Number — F302
Parameter Type —

Factory Default —
Off
Changeable During Run —
Yes
