Detailed description
2.3 Axis/spindle service display
Velocity actual value of active encoder (only 840Di)
Display of velocity actual value of the currently active encoder.
Velocity setpoint of drive (only 840Di)
Display of velocity setpoint of drive.
Speed actual value
The pulses supplied by the encoder are evaluated by the NC and displayed.
Unit: %
100% means maximum speed (corresponds to 10 V for analog interface; maximum speed
for SIMODRIVE 611 digital, specified by machine data:
MD1401 $MD_MOTOR_MAX_SPEED (speed for maximum useful motor speed).
Speed setpoint
Speed setpoint transferred to the drive (= speed setpoint from position controller and feed
forward control).
Unit: %
100% corresponds to the maximum speed setpoint (10 V for an analog interface, maximum
speed for SIMODRIVE 611 digital).
Spindle speed setpoint prog.
Speed setpoint programmed by the user.
Unit: rpm
e.g.: Input: S1000; display: 1000 rpm
Display applies to spindles only.
Spindle speed setpoint current
Current active speed setpoint with correct sign, including calculated compensation value and
any operative speed limitation (programmed by means of setting or machine data).
Unit: rpm
Display applies to spindles only.
Override
The effective correction factor of the feed or spindle correction switch is displayed.
