H9 ASD Installation and Operation Manual 133

Preset Speed 15

Program ⇒ Frequency ⇒ Preset Speeds
This parameter assigns an output frequency t o binary number 1111 and is
identified as Preset Sp eed #15. The binary number is applied to S1 – S4 of the
Termi nal B oar d to output the Preset Speed (see F018 for more information on
this parameter).
Direct Access Number — F294
Parameter Type — Numeri cal
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 puls e w idth 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 a bove, it cannot
be decreased below 2.0 kHz while running. If the PWM carrier
frequency is set at 1.9 kHz or bel ow, it c ann ot be inc rease d ab ove
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 — Numeri cal
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 cl osed
(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 Fai lure)
4 — Enabled (at Run)
Direct Access Number — F301
Parameter Type — Selection List
Factory Default — Off
Changeable During Run — No
