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-213) and Ref StopRmp (CP-210) or by the Dcl Rt RStp (CP-214). 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-270), 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
