Chapter 1 Detailed Drive Operation
Example Configuration 1:
This configuration sends the motor torque current reference value to a 0…10V
analog output signal.
• Parameter 831 [Anlg Out1 Sel] = 15 “Motor TrqRef ”
• Parameter 835 [Anlg Out1 Scale] = 0.1 per Volt
Motor torque is a per unit value where a value of 1 corresponds to 100% motor
torque. Therefore, parameter 831 [Anlg Out1 Scale] is set to 0.1 per 1V so that
when [Motor Torque Ref ] = 1 p.u., the analog output = 1 / 0.1 = 10V.
Example Configuration 2:
This configuration sends parameter 763 [Position Actual] out to a 0…10V analog
output signal.
• Parameter 831 [Anlg Out1 Sel] = 0 “User Select”
• Parameter 832 [Anlg Out1 DInt] is linked to parameter 763 [Position
Actual]
• Parameter 835 [Anlg Out1 Scale] is set to 214748364.7 per Volt
Parameter 763 [Position Actual] is an integer parameter with a range from
-2147483648 to +2147483647. Parameter 832 [Anlg Out1 DInt] is used
because parameter 763 [Position Actual] is an integer parameter.
Parameter 835 [Anlg Out1 Scale] is set to 214748364.7 per Volt so the analog
output will provide -10V when the position is -2147483647 and will +10V when
the position is +2147483647.
Auto/Manual
The Auto/Manual function on the LCD HIM is not functional on the
PowerFlex 700S drive with Phase II control.
