Forward Reverse 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:
Off
Disable Reverse Run
Disable Forward Run
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:
Disabled
Enabled
Carrier Frequency Control Mode
Program  Special  Carrier Frequency
This parameter provides for the automatic decrease of the carrier frequency.
Select 1 to decrease the Carrier Frequency setting as a function of an
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.
Settings:
No Decrease and No Limit
Valid Decrease and No Limit
No Decrease and Limit Small Pulse
Valid Decrease and Limit Small Pulse
Synchronized Deceleration Time
Program  Protection  Under-Voltage/Ridethrough
In the event that the Ridethrough function activates in a multiple-motor
application it will be necessary to manage the stopping motors synchronously
as not to damage the product being processed (e.g., wire spools, bobbin winder
for textile machines, etc.).
This parameter is used to minimize the product breakage during a momentary
power outage. This function stops multiple machines simultaneously or makes
them reach their respective command frequencies simultaneously by regulating
their deceleration times.
See parameter F302 for additional information on this setting.
