H-Stop (Stop and Hold) has the fifth highest operating priority. Use H-Stop to stop the drive with a
deceleration ramp. The velocity command is ramped down to “0”. If the loop is “Closed”, the ramp is
executed with velocity loop control (with feedforward, and Trim). If the loop is “Open”, the ramp will be
executed with feedforward only. The deceleration rate for the ramp is determined by Dcl Tm HStp (CP-307)
and Ref Ramps (CP-300) or by the Dcl Rt RStp (CP-308). When the velocity command reaches “0” and the
feedback is less than the Zero Speed (CP-370), then H-Stop will; hold the Control Output (SigU/SigW) to “0”
volts (Open Loop) or the dancer trimmed roll will hold the dancer in position near the Dancer SP (CP-250)
(Closed Loop) and the non-dancer trimmed roll's position (Closed Loop position hold).
To activate H-Stop:
• Activate High (Open), Level Sensitive, Latched
• Use momentary contact - does not need to be maintained to remain active
