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

Retry/Restart
This parameter adjusts the carrier frequency randomly. This feature is effective
in minimizing the negative effects of mechanical resonance.

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:
0 — No Decrease and No Limit
1 — Valid Decrease and No Limit
2 — No Decrease and Limit Small Pulse
4 — Valid Decrease and Limit Small Pulse
Direct Access Number — F316

Changeable During Run —
Yes
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
for additional information on this parameter.
Direct Access Number — F317
Parameter Type —
Numerical
Factory Default —
