S-DRIVE - PROGRAMMING PG DRIVES TECHNOLOGY
SK76745/10
The scooter manufacturer is responsible for ensuring that the controller is matched to the motor
resistance. Failure to do this may result in poor control characteristics, which in extreme
instances can make a scooter uncontrollable and potentially unsafe. PGDT accepts no liability for
losses of any kind arising from failure to comply with this condition
.
The scooter manufacturer is responsible for always ensuring that any replacement motors are
fully compatible with the originals that the controller was designed to match. Failure to do this
may result in poor control characteristics, which in extreme instances can make a scooter
uncontrollable and potentially unsafe. PGDT accepts no liability for losses of any kind arising
from failure to comply with this condition.
8.6 Motor Stall Timeout
If the Current Fold back Threshold is exceeded for the duration of Motor Stall Time, drive to the motor and will be cut the brake
engaged. Release the throttle back to neutral and try again. This feature can be used to protect the motor from undue stress.
Motor Stall Timeout is programmable between 0 (off) and 180 seconds.
8.7 Braking Current
This parameter sets the braking current of the S-Drive. The parameter is programmable from 45A to the controller’s maximum
rating. However, it is recommended the parameter is never set less than the controller’s maximum as shown in the table below.
This parameter should be set to a value suitable for the motor being used. PGDT accepts no
liability for losses of any kind arising from the improper use of the scooter or controller.
8.8 Timed Foldback Braking Current
This parameter sets the maximum braking current when the controller is in ‘Timed Foldback’ and can be used to protect the
motor. Reducing this parameter will result in a greater stopping distance for the scooter, so the parameter Timed Foldback
Speed should also be reduced in order to maintain a safe stopping distance.
This parameter should be set to a value suitable for the motor being used. PGDT accepts no
liability for losses of any kind arising from the improper use of the scooter or controller.
8.9 Timed Foldback Speed
This parameter can be used to limit the speed of the scooter when the controller is in ‘Timed Foldback’. The primary purpose of
this adjustment is to maintain a safe stopping distance if the braking current is reduced.
