The Skip Frequency function is used to avoid the TECDrive 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 TECDrive 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 TECDrive 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.

Edge-r
-
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.
: Following a Power On or Reset, the drive will automatically start if Digital Input 1 is closed.
To
: 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
.
Index 2 : Fire Mode Input Logic

0
-
Defines the operating logic when a setting of P-15 is used which includes Fire M, e.g. settings 15, 16 & 17.
0: Normally Closed (NC) Input
. Fire Mode active if input is open.
1: Normally Open (NO) Input
. Fire Mode active if input is closed
Index 3 : Fire Mode Input Type
0
1
0
-
Defines the input type when a setting of P-15 is used which includes Fire Mode, e.g. settings 15, 16 & 17.
0: 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, 1, 4 or 5 are used, the Keypad Start and Stop keys are active, and control terminals 1 and 2 must be linked together. Settings 2, 3,
6 and7 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 :-
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 reduced to P-58 for the time set in Index 1.
Note
If the drive is in Standby Mode prior to disable, the DC injection is disabled
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.
