H-Stop (Stop and Hold) has the third 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, using Kff ). If the loop is “Open”, the ramp will be
executed with feedforward only (using Kff). The deceleration rate for the ramp is determined by Dcl Tm
HStp (CP-312) and Ref StopRmp (CP-210) or by the Dcl Rt RStp (CP-311). H-Stop differs from R-Stop in
its operation after the deceleration ramp. The operation of the “Hold” function is dictated by Hstp
LoopMode (CP-230). In quadrature feedback, when the velocity command reaches “0” and the feedback is
less than the Zero Speed (CP-332), then H-Stop will; hold the CO Signal to “0” volts (Open Loop), hold the
feedback velocity to Zero Speed (Closed Velocity Loop) or hold the feedback position to the position where
the drive stopped (Closed Zero Error or Position Loop).
To activate H–Stop:
• Activate High (Open), Level Sensitive, Latched
• Use momentary contact - does not need to be maintained to remain active
