07.97 7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
Motor temperature
1702
Default value Lower output limit Upper output limit Units
0 0 32 767 °C
Active
at once
This machine data is used to display the motor temperature. The motor temperature is
measured by appropriate sensors and evaluated in the drive.
Lead time conver. motor meas. syst. (up to SW 4)
1703
Default value Lower output limit Upper output limit Units
0 0 32 767 µs
Active
at once
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.
Lead time conversion dir. meas. sys. (up to SW 4)
1704
Default value Lower output limit Upper output limit Units
0 0 32 767 µs
Active
at once
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.
Voltage setpoint (effective) (as from SW 6)
1705
Default value Lower output limit Upper output limit Units
– – – V
eff

Speed setpoint
1706
Default value Lower output limit Upper output limit Units
0.0 -100000.0 100000.0 rev/min
Active
at once
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.
