PG DRIVES TECHNOLOGY AC TRACTION – ADJUSTMENTS
The adjustable range is between 0Hz and 255Hz in 1.0Hz steps. The programmed value relates to the frequency output of the
controller, i.e. the motor’s stator speed.
If set to 1, then Inching Speed sets the speed of the vehicle (in both directions), that will be active when a switch connected to
pin 5 or pin 6 of Connector A is closed. The vehicle will not inch when the switch is open.
The adjustable range is 0Hz to 25Hz in 1.0Hz steps. The programmed value relates to the frequency output of the controller, i.e.
the motor’s stator speed.
1.7 Speed Limit 2 / Inching Time – (Speed 2/InchTime)
The function of this parameter is dependent on the setting of, 3.5 Connector A Pin 5 and 6, in the Controller Set-up menu. That
parameter sets whether pins 5 and 6 are used as speed limiting inputs or as inching control inputs.
If set to 0, then Speed Limit 2 sets the maximum speed of the vehicle when a switch connected to pin 6 on Connector A is open.
The speed limit is not applied when the switch is closed or a lower speed limit is in operation.
The adjustable range is between 0Hz and 255Hz in 1.0Hz steps. The programmed value relates to the frequency output of the
controller, i.e. the motor’s stator speed.
If set to 1, then Inching Time sets the period (in both directions), the vehicle will be moving for, when a switch connected to pin 5
or pin 6 of Connector A is closed. The vehicle will not inch when the switch is open.
The adjustable range is 0.1s to 10s in 0.1s steps.
For ease of adjustment, this parameter should be set to 0Hz before programming 3.5 Connector
A Pin 5 and 6 to ‘Inching’.
1.8 Speed Limit 3 – (Speed 3)
The function of this parameter is dependent on the setting of, 3.6 Connector A Pin 7, in the Controller Set-up menu.
If set to 0, then Speed Limit 3 sets the maximum speed of the vehicle when a switch connected to Pin 7 on Connector A is open.
The speed limit is not applied when the switch is closed or a lower speed limit is in operation.
If set to 1, then Speed Limit 3 sets the maximum speed of the vehicle when a switch connected to Pin 7 on Connector A is
closed. The speed limit is not applied when the switch is open or a lower speed limit is in operation. Please note, that even if this
parameter is set to 0Hz, the controller will continue to pulse whilst the Foot Switch is closed. This is designed to avoid rollback on
gradients.
The adjustable range is 0Hz to 255Hz in 1.0Hz steps. The programmed value relates to the frequency output of the controller, i.e.
the motor’s stator speed.
1.9 Direction Regen. Braking – (DBrake)
This sets the strength of the braking upon a direction change. The setting is a percentage of the Braking Direction Slip parameters,
4.22 & 4.23 and the Braking Slip parameters 4.24 & 4.25, in the Motor Set-up menu.
The adjustable range is 0% to 100% in 1.0% steps.
This parameter has no effect in Speed Control mode.
1.10 Neutral Regen. Braking – (NBrake)
This sets the strength of the braking when the vehicle is in neutral, i.e. no drive signal in either direction. The setting is a percentage
of the Braking Slip parameters, 4.24 & 4.25 and the Braking Neutral Slip parameters 4.28 & 4.29 in the Motor Set-up menu.
The adjustable range is 0% to 100% in 1.0% steps.
This parameter has no effect in Speed Control mode.
