Preset Speed 15
Program Frequency 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
F018
for additional information on this parameter.
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.
Auto Restart Selection
Program Protection 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 — All Starts (Enabled at Run)
