Over-travel Sequence
Over-travel limit inputs are provided on CN1. The positive rotation over-travel (PROT)
limit input is on pin CN1-32 and the negative rotation over-travel (NROT) limit is on pin
CN1-33. This condition is not an alarm. The timing diagrams below define the sequence
of operation for over-travel conditions. Func0 (Mode 2, Bit 5), may be used to change
the sense of the NROT and PROT.
Notes:
1. The operation of the command invalidation differs between position and velocity
controls. For position controls, command pulses are inhibited, and for velocity
controls, the command is forced to 0 (VCMD=0). These settings are valid when the
acceleration/deceleration time (Tvac, Tvde) or low pass filter (VLPF) parameters are
set.
2. Setting the Sequence Current Limit (SILM) parameter using the Remote Operator
(Mode 1, Page 12) can change sequence current limit values.
