7 Drive Machine Data (SIMODRIVE Drive MD) 07.97
7.3.2 Drive MD (data description)
Configuration structure 1004
Default value Lower input limit Upper input limit Units
0000 0000 7FFF Hex
Active on
Power On
Input of the configuration for control structures, speed measuring systems and functionality
referred to the SIMODRIVE System 611D.
Value table:
Bit 0 Speed torque feedforward channel
of drive 0 = Not active
1 = Active
Bit 1 Not assigned
Bit 2 Higher dynamic response (single
axis module only) 0 = Current before speed control
calculation
1 = Speed before current control
calculation
Bit 3 Reserved
Bit 4 Integrator control (as from SW 6) 0 = Integrator control in speed
controller active. The integrator
is stopped when the current or
voltage setpoint reaches the
limit.
1 = Integrator control in speed
controller not active. Value
limited to 2x the torque limit.
Always active with ”Travel to
fixed stop”.
Bit 5-15 Not assigned
Caution:
Speed before current control is possible only with one active axis on the module.
The default is: current before speed control (bit 2 = 0).
No. encoder marks motor measuring system 1005
Default value Lower input limit Upper input limit Units
2 048 128 8 192 Incr/rev
Active on
Power On
Input of number of encoder increments per motor revolution of the motor measuring system.
Note:
The indirect measuring system must always be configured for FDD/MSD.
(Not for pure AM/Vf operation)
No. encoder marks direct measuring system 1007
Default value Lower input limit Upper input limit Units
0 0 65 535 Incr/rev, incr/mm
Active on
Power On
Input of the encoder increments per revolution for a linear or rotary direct measuring system.
Note:
Value 0 in the display means that no direct measuring system is available. This MD is currently
of no importance.
