S-DRIVE - PROGRAMMING PG DRIVES TECHNOLOGY
SK76745/10
7.19 Inhibit 2 Horn Input Enable Tone
This parameter sets the tone when the alarm is active. The parameter can be programmed to 0, 1, 2 or 3.
0 - Self Resonating 1 - 2khz 2 - 1kHz 3 - 500hz
8 Motor Parameters
8.1 Current Limit
Will allow the min and max current limits to be altered in 1 Amp steps between 10 and 60A if dependencies permit.
Max Sets the continuous current output of the S-Drive.
Min Sets the current output of the S-Drive when it is at 80°C. Refer to section 8.4.
8.2 Boost Drive Current and Boost Drive Time
These parameters provide a current boost for a set length of time if the controller recognizes a drive requirement which causes
the motors to require more current, such as when the scooter is being driven up a hill. Refer to the following graph.
The drive boost current can be set in 1A steps between 10 and 140A but not less than the ‘current limit max’ setting, and the drive
boost time to be altered in 1 second steps between 0 and 10 seconds.
The maximum values for these parameters are shown in the table below.
8.3 Current Foldback Threshold, Current Foldback Time, Current Foldback Level, Motor Cooling Time
The parameters Threshold, Time, Level and Motor Cooling can be used to protect the motor from overheating. If the motor
current exceeds the value set by Threshold for a period set by Time, then the S-Drive’s current output will be reduced to a value
set by Level. After this has occurred, full current is only permissible after a time period set by Motor Cooling.
Threshold Adjustable between 1A and the value of Current Limit Max. in steps of 1A.
Time Adjustable between 0s and 250s in steps of 1s.
Level Adjustable between 0% and 100% in steps of 1%.
Motor Cooling Adjustable between 0s and 3825s in steps of 15s.
This is useful for protecting motors against potential damage when the scooter is being used on a long gradient.
Example Current Limit Max.= 60A, Threshold = 40A, Time = 30s, Level = 50% and Motor Cooling = 150s.
