Axis %1 Measuring System Changing; Axis %2 Hardware Limit Switch %3; Axis %2 Taken From Traverse Mode To Follow-Up Mode - Siemens Sinamics S120 Diagnostic Manual

Remedy: Please inform the authorized personnel/service department.
Check the interface signals DB380x DBX0002.1 (Servo enable), DB380x DBX4001.7 (Pulse enable), check the drive
signals DB390x DBX4001.7 (Pulses enabled), DB390x DBX4001.5 (Drive ready) for example with the PLC status dis-
play in the DIAGNOSTICS operating area. Check the encoder selection (for axes) as well as other signals enabling
motion (such as SIMODRIVE 611D terminal 663 etc.) according to the drive type used.
When the terminal enables of the drive have failed, trace back the wiring or hardware function (for example relay func-
tion) or proceed as stated in the relevant drive documentation.
With SAFETY: With active actual-value linkage, output of the error message on the slave axis can be prevented by
increasing MD36060 $MA_STANDSTILL_VELO_TOL (default value is 5 mm).
Program Clear alarm with the Delete key or NC START.

Axis %1 measuring system changing

Parameters: %1 = Axis name, spindle number
Definitions: The measuring system for this axis is changing.
Reaction: Alarm display.
Remedy: -
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
21614 [Channel %1: ] Axis %2 hardware limit switch %3
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = String (+, - or +/-)
Definitions: The signal DB380x DBX1000.1 und .0 (Hardware limit switch plus/minus) has been set at the NC/PLC interface.
Reaction: NC Start disable in this channel.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
1. With axes that have already been referenced, the software limit switch 1 or 2 should respond before the hardware
limit switch is reached. Check MD36110 $MA_POS_LIMIT_PLUS, MD36100 $MA_POS_LIMIT_MINUS, MD36130
$MA_POS_LIMIT_PLUS2 and MD36120 $MA_POS_LIMIT_MINUS2 and the NC/PLC interface signal for the selec-
tion DB380x DBX1000.3 / 1000.2 (1st/2nd software limit switch plus/minus) and correct, if necessary (PLC user pro-
gram).
2. If the axis has not yet been referenced, it is possible to depart from the hardware limit switch in the opposite direction
in JOG mode.
3. Check the PLC user program and the connection from the switch to the PLC input module, provided the axis has
not reached the hardware limit switch at all.
Program Clear alarm with the RESET key. Restart part program
Continuation:
21615 [Channel %1: ] Axis %2 taken from traverse mode to follow-up mode
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: This axis has been taken from traverse mode and put into "Follow-up" mode, for instance because the pulse enable
for the drive has been reset.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
