7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
1004
Default value
0000
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
Bit 1 Not assigned
Bit 2 Higher dynamic response (single
axis module only)
Bit 3 Reserved
Bit 4 Integrator control (as from SW 6)
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).
1005
No. encoder marks motor measuring system
Default value
2 048
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)
1007
No. encoder marks direct measuring system
Default value
0
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.
