PG Drives Technology SIGMADRIVE Series User Manual

AC TRACTION – MOTOR SET-UP PG DRIVES TECHNOLOGY
1.1 Motor Temperature Cutback – (TempStrt)
This sets the point at which the controller will begin to reduce its current output, in order to protect the motor. The temperature is
measured by the motor’s thermal sensor, which provides feedback via pin 4 of Connector C. The output will reduce linearly to
zero at a point set by the value of this parameter plus 10ºC.
The adjustable range is 1°C to 151°C in 1°C steps.
If set to 151°C, then the function will be disabled and no reduction in current will occur.
1.2 Motor to Vehicle Speed Ratio – (SpdRatio)
This sets the relationship between the rotational speed of the motor and the actual driving speed of the vehicle, i.e. the overall
vehicle gear ratio. This information, in conjunction with parameter, 1.30 Max. Vehicle Speed, is used to set the speed display on
the Sigmagauge.
The value of this parameter should be the result of dividing the motor’s speed in units of rpm by the vehicle’s speed in units of
kph.
Example: if a vehicle speed of 15kph corresponds to a motor speed of 3000rpm, then the value of this parameter should be
3000/15 = 200.
The adjustable range is 1.0 to 999.9 in 0.1 step increments.
1.3 Number of Teeth – (SpdTeeth)
This sets the number of pulses, i.e. teeth on the encoder that correspond to one motor revolution.
The adjustable range is 1 to 255 in 1 step increments.
After the value has been changed, the keyswitch must be cycled for the new value to be accepted.
1.4 Number of Motor Poles – (SpdPoles)
The value of this parameter should be set to correspond to the number of motor poles.
There are two programmable options – 4 or 6.
After the value has been changed, the keyswitch must be cycled for the new value to be accepted.
