Boundary conditions
Axis replacement
The function "axis interchange" allows that an axis/spindle is known in several channels and
can be programmed from this alternating (see Section "Axis/spindle replacement
(Page 320)").
In conjunction with the functions "program test" and "channel-by-channel running-in", the
following must be observed for an axis interchange:
● If only one of the channels is in the "program test" state, then the interchanged axis is
● For a program test, for end of part program/reset, for all axes/spindles that do not
Note
The programs should also include a WAIT tag at the end in order that they are
simultaneously exited.
Examples
Example 1: Channel 2 is to be tested in a 3-channel system.
The following program test sequences are possible:
a) Program test without SERUPRO
1. The user decides which axes/spindles should actually be physically traversed. "Suppress
2. The "program test" state is selected for channels 1 and 3.
3. Channels 1, 2 and 3 are started via the PLC.
4. "Program test" can be selected again after the end of the program.
5. If the actual setting of "suppress program test" is also practical for other situations
b) Program test with SERUPRO
1. The user decides which axes/spindles should actually be physically traversed. "Suppress
2. The "program test" state is selected for channels 1 and 3.
3. Channels 1, 2 and 3 are started via the PLC.
4. A fault or an alarm occurs, the user interrupts with RESET.

taken from this channel and is inserted in a channel that is not in the "program test" state.
For an interchanged axis with active axis disable, for a change via the channels
with/without channel state "program test", then the state in the axis itself does not change
(see example 3).
interpolate, resynchronization is made at the actual servo position. As a consequence, for
an axis interchange that is first made after the end of the program, as the axis may only
exit the channel at the end of the program, the simulated position reached is not
transferred to the accepting channel.
program test" is set for these axes.
(channel 1 or channel 3 are to be tested), then this signal can remain set. This is certainly
practical in many cases.
