Toshiba H9 operation manual F294, PWM Carrier Frequency, Auto Restart Selection

F294	F301
Preset Speed 15	Direct Access Number — F294
Program ⇒ Frequency ⇒ Preset Speeds	Parameter Type — Numerical
This parameter assigns an output frequency to binary number 1111 and is	Factory Default — 0.00
	Changeable During Run — Yes
identified as Preset Speed #15. The binary number is applied to S1 – S4 of the
	Minimum — Lower Limit (F013)
Terminal Board to output the Preset Speed (see F018 for more information on
this parameter).	Maximum — Upper Limit (F012)
	Units — Hz
PWM Carrier Frequency	Direct Access Number — F300
Program ⇒ Special ⇒ Carrier Frequency	Parameter Type — Numerical
This parameter sets the frequency of the pulse width modulation signal applied	Factory Default — 2.200
	Changeable During Run — No
to the motor.
Note: When operating in the Vector Control mode the carrier	Minimum — 1.0
	Maximum — (ASD-dependent)
frequency should be set to 2.2 kHz or above.
	Units — kHz

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

2.0kHz 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 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
