H9 ASD Installation and Operation Manual 133
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 more information on
this parameter).
Direct Access Number — F294
Parameter Type — Numerical
Factory Default — 0.00
Changeable During Run — Yes
Minimum — Lower Limit (F013)
Maximum — Upper Limit (F012)
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
Auto Restart Selection
Program ⇒ Protection ⇒ Retry/Restart
This parameter Enables/Disables the ability of the drive 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
Parameter Type — Selection List
Factory Default — Off
Changeable During Run — No
