FM 453 Servo Drive / Step Drive Positioning Module
C79000-G7076-C453-01
All machine data of the FM 453 are listed in Table 5-5.
Notes to the machine data list:
K stands for configuration data: see Section 9.3.3
E stands for user-definable machine data settings for readjustment (startup
optimization) and technology; see
Section 9.3.3
The units of measurement refer to the value representation in the machine
data DB.
