For the feedback message "Speed reached", the ‚Declared Velocity‛ is set to zero and
only a message range is placed in the ‛Message Window‛.
General Information
The general limitations and settings via FCT are also valid during synchronization.
Axle limitations, speeds, accelerations, message windows, etc.
Up to
FW 1.2.0.1.2:
During resynchronization on a forward-running master, the
message "Setpoint reached" comes as soon as the speed within the set message
window is reached. If overshooting occurs during the catch-up phase or the message
window is set too low, the message may come several times or flicker.
Starting with
FW 1.3.0.1.7
, the message "Position synchronized" is output at DOUT2.
The deviation is configured via the tolerance window for "Motion Complete" in the
FCT.

I/O functions and device control
Limit switch
The limit switches serve to limit the range of motion for safety reasons. During homing,
one of the two limit switches can serve as reference points for positioning control.
Sample input
If a field bus is used for activation, a high-speed sampling input is available for time-
critical tasks for various applications (position sensing, special applications, ...).
Analogue input
The CMMS-ST stepping motor controller has an analogue input for input levels ranging
from +10 VDC to -10 VDC. The input is a differential input (12 bit), ensuring a high degree
of protection against interference. The analogue signals are quantified and digitalised by
the analogue-digital converter at a resolution of 12 bits. These analogue signals serve to
specify setpoints (speed or torque) for the control.
MODE switching
The analogue input AIN0 is also available as a digital input for use of further functions
such as the jog function, record linking and synchronization. MODE switching allows you
to switch between the following default settings:
Mode

Mode 0
Positioning
Mode 1
