Preset Speeds
This parameter assigns an output frequency to binary number 1111 and is
identified as
Preset Speed 15
. The binary number is applied to
S1
–
S4
of the
Terminal Board
to output the
Preset Speed
.
See
for additional information on this parameter.
Direct Access Number — F294
Parameter Type —

Factory Default —
0.00
Changeable During Run —
Yes
Minimum — Lower-Limit Freq. (

Maximum — Upper-Limit Freq. (
Units — Hz
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.
Direct Access Number — F300
Parameter Type —
Numerical
Factory Default —
2.200
Changeable During Run —
No
Minimum — 1.0
Maximum — (ASD-Dependent)
Units — kHz

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).
Settings:
0 — Off
1 — Enabled (at Power Failure)
2 — Enabled (at Make-Break ST-CC)
3 — Enabled (at Make-Break ST-CC or Power Failure)
4 — Enabled (at Run)
Direct Access Number — F301
