The Skip Frequency function is used to avoid the Optidrive operating at a certain output frequency, for example at a frequency
which causes mechanical resonance in a particular machine. Parameter P-27 defines the centre point of the skip frequency band,
and is used in conjunction with P-26. The Optidrive output frequency will ramp through the defined band at the rates set in P-03 and
P-04 respectively, and will not hold any output frequency within the defined band. If the frequency reference applied to the drive is
within the band, the Optidrive output frequency will remain at the upper or lower limit of the band.

This parameter in conjunction with P-28 sets a frequency point at which the voltage set in P-29 is applied to the motor. Care must be
taken to avoid overheating and damaging the motor when using this feature.

Start Mode, Automatic Restart, Fire Mode Configuration
Index 1 : Start Mode & Automatic Restart
Selects whether the drive should start automatically if the enable input is present and latched during power on. Also configures the
Automatic Restart function.

Following Power on or reset, the drive will not start if Digital Input 1 remains
closed. The Input must be closed after a power on or reset to start the drive.

. In addition, following a trip, the drive will make up to 5 attempts
to restart at 20 second intervals. The numbers of restart attempts are
counted, and if the drive fails to start on the final attempt, the drive will trip
with a fault, and will require the user to manually reset the fault. The drive
must be powered down to reset the counter

Maintained Input
The drive will remain in Fire Mode, only as long the fire mode input signal remains (Normally
Open or Normally Closed operation is supported depending on Index 2 setting).
1
Momentary Input
Fire Mode is activated by a momentary signal on the input. Normally Open or Normally Closed
operation is supported depending on Index 2 setting. The drive will remain in Fire Mode until
disabled or powered off.

This parameter is active only when operating in Keypad Control Mode (P-12 = 1 or 2) or Modbus Mode (P-12 = 3 or 4). When settings
0 or 1 are used, the Keypad Start and Stop keys are active, and control terminals 1 and 2 must be linked together. Settings 2 and 3
allow the drive to be started from the control terminals directly, and the keypad Start and Stop keys are ignored.

Index 1:
Defines the time for which a DC current is injected into the motor. DC Injection current level may be adjusted in P-59.
Index 2 :
Configures the DC Injection Function as follows :-
Setting Function
Description
0
DC Injection on Stop
DC is injected into the motor at the current level set in P-59 following a stop command,
after the output frequency has reached 0.0Hz for the time set in Index 1. This can be
useful to ensure the motor has reached a complete stop before the drive disables.
1
DC Injection on Start
DC is injected into the motor at the current level set in P-59 for the time set in Index 1
immediately after the drive is enabled, prior to the output frequency ramping up. The
output stage remains active during this phase. This can be used to ensure the motor is at
standstill prior to starting.
2
DC Injection on Start & Stop
DC injection applied as both settings 0 and 1 above.
