Parameters
5.5 Analog I/O
5.5.1 Analog Output
The PositionServo has one analog output with 10-bit resolution on P3 pin 23. The signal is scaled to ±10V.
The analog output can be assigned to the following functions:
• Not Assigned
• Phase current RMS
• Phase current Peak
• Motor Velocity
• Phase R current
• Phase S current
• Phase T current
• Iq current (Torque component)
• Id current (Direct component)
5.5.2 Analog Output Current Scale (Volt/Amps)
Applies scaling to all functions representing CURRENT values.
5.5.3 Analog Output Velocity Scale (mV/RPM)
Applies scaling to all functions representing VELOCITY values. (Note: that mV/RPM scaling units are
numerically equivalent to volts/kRPM)
5.5.4 Analog Input Current Scale (Amps/Volt)
This parameter sets the analog input sensitivity for current reference used when the drive operates in torque
mode. Units for this parameter are A/Volt. To calculate this value use the following formula:
Iscale = Imax / Vin max
Imax maximum desired output current (motor phase current RMS)
Vin max max voltage fed to analog input at Imax
Example: Imax = 5A (phase RMS)
Vin max = 10V
Iscale = Imax / Vin max
= 5A / 10V = 0.5 A / Volt (value to enter)
5.5.5 Analog Input Velocity Scale (RPM/Volt)
This parameter sets the analog input sensitivity for the velocity reference used when the drive operates
in velocity mode. Units for this parameter are RPM/Volt. To calculate this value use the following formula:
Vscale = VELOCITYmax / Vin max
VELOCITYmax maximum desired velocity in RPM
Vin max max voltage fed to analog input at Velocity
max
Example: VELOCITYmax = 2000 RPM
Vin max = 10V
Vscale = VELOCITYmax / Vin max
= 2000 / 10V
= 200 RPM / Volt (value to enter)
