Forward Run/Reverse Run Disable
Program ⇒ Frequency ⇒ Forward/Reverse Disable
This parameter Enables/Disables the Forward Run or Reverse Run mode.
If either direction is disabled, commands received for the disabled direction will not be recognized.
If both directions are disabled, the received direction command will determine the direction of the motor rotation.
Settings:
0 — Off
1 — Disable Reverse Run
2 — Disable Forward Run
Direct Access Number — F311
Parameter Type — Selection List
Factory Default — Off
Changeable During Run — No
Random Mode
Program ⇒ Protection ⇒ Retry/Restart
This parameter adjusts the carrier frequency randomly. This feature is effective in minimizing the negative effects of mechanical resonance.
Settings:
0 — Disabled
1 — Enabled
Direct Access Number — F312
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
Carrier Frequency Control Mode | Direct Access Number — | F316 | |
Program ⇒ Special ⇒ Carrier Frequency | Parameter Type — Selection List | ||
This parameter provides for the automatic decrease of the carrier frequency. | Factory Default — Valid Decrease and | ||
No Limit |
| ||
Select 1 to decrease the Carrier Frequency setting as a function of an | Changeable During Run — Yes | ||
increased current requirement. |
|
| |
Selection 2 or 3 may also include an output voltage drop as a function of an |
|
| |
increased current requirement. The Carrier Frequency should be set below |
|
| |
4 kHz. |

for textile machines, etc.). | Maximum — 6000.0 |

This parameter is used to minimize the product breakage during a momentary | Units — Seconds | |
power outage. This function stops multiple machines simultaneously or makes | ||
| ||
them reach their respective command frequencies simultaneously by regulating |
| |
their deceleration times. |
