    1. Short Description Whilst the P8511-000-P with option Analogue-output is specifically designed to provide closed loop (Proportional, Integral, Differential) analogue control of 4 quadrant drives, it also serves the purpose of operating as a 2 or 3 speed controller, as the P8511-000-R. When used as a closed loop controller, it is essential that: - 1.

  • Page 21 Parameters for Analogue (PID) Control (R50-R58) Speed (input in rpm, referred to Encoder) The maximum speed is set in this Register, in rpm. The speed is monitored by the Encoder speed (1 – 10000 rpm). Should there be gearing between motor and Encoder, this must be considered in the calculation to set R50.

  • Page 25 Offset Adjustment of Closed loop Analogue system When the position controller is connected to the motor drive, it is possible to come “into position” with an error, due to an analogue offset voltage. This error can be compensated for by adjusting the offset potentiometer of the drive (analogue drives).

  • Page 26: Setting Of Analogue Parameters

    Setting of Analogue Parameters Initial settings :- 1. Enter Encoder Resolution in R57 (max 10000 ppr) 2. Set Edge Multiplier in R56 3. Set the desired speed in R50 (for programme and single) and R60-63 (for Hand) – max 10000 rpm. The product of Encoder Resolution and rpm should not exceed the maximum input frequency of the controller.
