SK76745/10 
1  Introduction 
This chapter gives an overview of the programmable parameters within the S-Drive Controller. The S-Drive can be programmed 
with a SP1a handheld programmer or a PG Drives Technology PC Programmer.  
This chapter does not give details of how to make adjustments, for these details please refer to the relevant documentation for 
the programmer you are using.  
Programming  should  only  be  conducted  by  healthcare  professionals  with  in-depth  knowledge  of 
PGDT controllers. Incorrect programming could result in an unsafe set-up of a scooter for a user. 
PGDT accept no responsibility for losses of any kind if the programming of the control system is 
altered from the factory pre-set values. 
1.1  SP1a Programmer 
The SP1a handheld programmer is intended to give dealers and therapists access to the programmable parameters which can 
be used to adjust the scooter to an individual user. These parameters are: 
Acceleration      Deceleration 
Forward Speed      Reverse Speed 
Throttle Invert      Sleep Timer 
Read System Log      Read Timer 
The SP1a can also be used to Read Trip Log and Read Timer. For details of how to use the SP1a with the S-Drive, refer to the SP1a 
Programming and Diagnostics guide, SK73762. 
1.2  PC Programmer 
There are two versions of  the PC Programmer  – one for dealers and therapist which gives the same access level as the SP1a 
handheld programmer; and one for scooter OEMs which gives access to all S-Drive Controller parameters. These are known as 
PCPa and PCPb respectively.  
For details of how to use these software packages with the S-Drive, refer to the documentation supplied with the software.
