AC TRACTION – ADJUSTMENTS PG DRIVES TECHNOLOGY
1.1 Acceleration – (Accel)
This sets the time taken to accelerate from zero torque demand to maximum torque demand in Torque Control mode, or zero
speed to maximum speed in Speed Control mode.
The maximum torque demand is set from the motor set-up table.
The maximum speed demand is set by 1.4 Maximum Forward Speed and 1.5 Maximum Reverse Speed.
Increasing the value results in a slower vehicle acceleration, while decreasing the value results in a faster vehicle acceleration.
The adjustable range is 0.1s to 10.0s in 0.1s steps.
1.2 Deceleration – (Decel)
This sets the time taken to decelerate from maximum torque demand to zero torque demand in Torque Control mode, or
maximum speed to zero speed in Speed Control mode.
Increasing the value results in a slower vehicle deceleration, while decreasing the value results in a faster vehicle deceleration.
The adjustable range is 0.1s to 10.0s in 0.1s steps.
1.3 Creep Speed – (Creep)
This effectively sets the initial speed that the vehicle will adopt on entering drive.
Increasing the value will help minimise any delay from selecting drive to creeping the vehicle. The value relates to the frequency
output of the controller, i.e. the motor’s stator speed.
The adjustable range is 0Hz to 63.0Hz in 0.0625Hz steps.
1.4 Maximum Forward Speed – (SpdMaxF)
This sets the maximum forward speed of the vehicle. The programmed value relates to the frequency output of the controller, i.e.
the motor’s stator speed.
The adjustable range is 0Hz to 255Hz in 1.0Hz steps.
Maximum Forward Speed must not be set to a higher value than the parameter 4.8 Motor Speed
Maximum, in the Motor Set-up menu. The 4.8 Motor Speed Maximum setting should always be
programmed at least 10% higher than this setting.
1.5 Maximum Reverse Speed – (SpdMaxR)
This sets the maximum reverse speed of the vehicle. The programmed value relates to the frequency output of the controller, i.e.
the motor’s stator speed.
The adjustable range is 0Hz to 255Hz in 1.0Hz steps.
Maximum Reverse Speed must not be set to a higher value than the parameter 4.8 Motor Speed
Maximum, in the Motor Set-up menu. The 4.8 Motor Speed Maximum setting should always be
programmed at least 10% higher than this setting.
1.6 Speed Limit 1 / Inching Speed – (Speed 1/InchSpd)
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 1 sets the maximum speed of the vehicle when a switch connected to pin 5 on Connector A is open.
The speed limit is not applied when the switch is closed or a lower speed limit is in operation.
