FM 453 Servo Drive / Step Drive Positioning Module
C79000-G7076-C453-01
See Section 5.3.1 for further applications.
The zero position signal of the drive power section can be connected for each
channel to a further input.
The zero position signal is specified in MD37 (see Section 5.3.1) and can be
one of the following (see Section 9.7):
S
Current-sourcing pattern zero signal for reference point approach
S
Zero pulse, external (e.g. reference point switch signal) for reference
point approach
The standby signal 2 (controller ready) of the drive power section can be con-
nected for each channel to a further input.
The message signal is specified in MD37 (see Section 5.3.1).
Note
The “READY2” input is configured as an isolated optical coupler input. See
Section 4.7 for details about wiring.
