The parameter object CfgSpindle is not required for:
Axes that are not defined as spindles (not entered in MP_spindleIndices)
Virtual axes (MP_axisMode = Virtual)
Axes that are for display only (MP_axisMode = Display)
A spindle that is not driven in a position control loop can also be stopped at a
defined position (trip dog position). It is a prerequisite that this position be
reported to a fast PLC input. A fast PLC input is not read in PLC cycle time but
in the IPO clock.
On HSCI controls, a vacant PLC input on the PL 62xx PLC system module or
a vacant PLC input of the UEC 11x is used as the input for the spindle
reference signal. Use one of the first two slots from the left on the PL 62xx.
Use the IOconfig PC software to determine a vacant PLC input and identify its
input number.
During a spindle stop, the PLC transfers the rotational speed for "waiting for
the input signal" (see "Module 9414 Position the spindle" on page 1027) in
Module 9414.
The spindle is stopped in three steps.
1 The spindle is decelerated until the defined rotational speed is reached.
2 The spindle continues rotating at the defined rotational speed.
3 The spindle is stopped immediately (without ramp) as soon as the input
signal of the spindle trip dog is detected.
