1702
Default value
0
This machine data is used to display the motor temperature. The motor temperature is
measured by appropriate sensors and evaluated in the drive.
1703
Lead time conver. motor meas. syst. (up to SW 4)
Default value
0
This machine data is used to display or diagnose the lead time for the motor measuring
system converters. A converter lead time is required if the converter times are greater than the
ASIC cycle time. This machine data is valid only for indirect measuring systems.
1704
Lead time conversion dir. meas. sys. (up to SW 4)
Default value
0
This machine data is used to display or diagnose the lead time for the motor measuring
system converters. A converter lead time is required if the converter times are greater than the
ASIC cycle time. This machine data is valid only for direct measuring systems.
1705
Voltage setpoint (effective) (as from SW 6)
Default value
–
Voltage setpoint display. The signal can be output via DAC.
2 qset 2 dset
MD 1705 = U + U
1706
Default value
0.0
This machine data is used to display the speed setpoint which represents the unfiltered
summation setpoint. It comprises the component of the position controller output and the
speed feedforward control arm. Time-synchronous unlatching (scanning) of machine data MD
1706, MD 1707 and MD 1708 is not provided. The appropriate machine data is unlatched by
the read request of the non-cyclical communications protocol.
