Feed drive This display field describes the currently selected FDD drive as selected via soft-
keys drive +/–.
Ramp-up phase This display field contains the control word for the ramp-up control of the 611D
components and exists for each logical digital drive number (drive MD 11000).
The ramp-up state set by the SERVO is shown in the high byte and the state ack-
nowledged by the drive is shown in the low byte (see description drive status).
Pulse enable This display field contains the status of CI 63/48 of the infeed/regenerative
(terminal 63/48) feedback unit. (Drive MD 1700.2 – pulse suppression for all drives).
Possible display range: off or on
Drive enable This display field contains the status of terminal 64 of the infeed/regenerative
(terminal 64/63) feedback unit. (Drive MD 1700.6 – for all drives).
Possible display range: off or on
Pulse enable This display field contains the status of terminal 663 (drive MD 1700.1
(terminal 663) – module-specific pulse suppression).
Possible display range: off or on
Pulse enable PLC This display field contains the status of the pulse enable PLC of the cyclic
setpoint control word 2 (drive MD 11005.7).
Possible display range: off or on
Speed controller This display field shows the condition of the speed controller enable NC of cyclic
enable setpoint control word 2 (drive MD 11005.9).
Possible display range: off or on
Set of setpoint This display field contains the current set parameter set of cyclic control word 2
parameter (drive MD 11005.0–2).
Possible display range: 0 – 7
CRC error This display field contains the number of bus transmission errors between NC
and drive detected by the hardware (drive MD 11001).
Possible display range: 0000 – FFFF
Message ZK1 This display field contains the state of message state class 1 of cyclic status
word 1 (drive MD 11002.0).
Possible display range: off or on
Pulse enable actual This display field contains the state of enabled pulses of cyclic status word 2
(drive MD 11003.7).
Possible display range: off or on
DC link This display field contains the status of the DC link (drive MD 11006.0).
Possible display range: off or on
Actual parameter set This display field contains the current actual parameter set of cyclic status word 2
(drive MD 11003.0–2).
Possible display range: 0 – 7
Position actual value This display field contains the current positional actual value (SW 4: drive MD
12000). It is dependent on the position control of the rotary axis (NC MD 5640.5)
and position control resolution (NC MD 18000.0–3).
Speed actual value This display field contains the current speed actual value of the motor (drive MD
1707).
Speed setpoint This display field contains the current speed setpoint of the motor (drive MD
1706).
Capacity utilization This display field shows the capacity utilization of the feed drive. Up to the rated
(SW 4) speed, the ratio of torque to maximum torque is displayed, and above the rated
speed the ratio of power to maximum power is displayed (drive MD 1722).
