494 Motion Variables
An out-of-tolerance registration event is one that occurs outside the target
position or nominal length tolerance entered in the Configure Cam block,
as shown below.
PCAM_bad_registration_count is incremented when an out-of-tolerance
registration event occurs. It is reset to zero when an in-tolerance
registration event occurs. As shown above, all registration events, which
occur after a good registration event and before the beginning of the next
tolerance area, are considered bad—even if they occur within the current
tolerance.
PCAM_bad_registration_count is set to zero when power is applied to the
motion controller. It can be reset to zero (or any other value) using the
equation block.
Axis Iq Reference 1394
The Axis_iq_reference_1394 variable reports the instantaneous torque/
current that the controller commands to the designated axis module, as a
percent of rated current.
