9-54
FM 453 Servo Drive / Step Drive Positioning Module
C79000-G7076-C453-01
9.3.13 Application Data (Job No. 105)
The values passed with “request application data” job no. 18 (see Section
9.3.7) are returned from the FM 453.
These values are always updated in the module cycle on the FM 453.
9.3.14 Actual Value Block Change (Job No. 107)
The “actual value block change” function is described in Section 10.1, G50,
G88, G89.
9.3.15 Servicing Data (Job No. 108)
The following display data of the measuring circuit are servicing data:
S
DAC output value [mV] (for servo drive) or
frequency output value [Hz] (for step drive)
S
Actual encoder value [MSR] (for drive with encoder) or
pulse output counter (0...2
16
-1) [pulse] (for drive without encoder)
S
Pulse errors (for drive with incremental encoder)
S
K
v
factor (position control loop gain) (for servo drive)
S
Following error [MSR] (for servo drive) or
difference between setpoint and actual positions [MSR] (for step drive)
S
Following error limit [MSR] (for drives with encoders)
S
s Overshoot/Switch readjustment in Reference Point Approach mode
[MSR]
S
Approach time Te [ms]/drive time constant Ta [ms] in “Open-loop con-
trol” mode (for servo drive)
