16 Commissioning and Start-up Procedure
This section describes the commissioning procedure for the controls step-by-step. The precise
descriptions of the functions may be found by referring to the appropriate sections.
16.1 Code numbers for commissioning
Certain operating conditions and functions for the commissioning procedure must be selected by
code numbers (see Section "Display and operation").
Code number Function
9 51 48 List of machine parameters (see Chapter "Machine parameters")
80 76 67 PLC operation (see Chapter "PLC programming")
53 12 10 Cancel markers M1000 to M2000 and B0 to B127
7 53 68 Automatic offset adjustment (see Section "Servo positioning")
10 52 96 Non-linear axis error compensation (see Section 1.6.4)
16.2 Preparation of the machine
The machine is prepared without a control being connected.
Follow the sequence below to commission the drive amplifiers:
– Clamp the nominal value lead to 0 V:
Disconnect and short together the nominal value inputs of the drive amplifiers.
0 V must be applied to the input.
– Connect the servo-enable input:
Connect the servo-enable input to 24 V, thus activating the servo.
– Connect the power supply to the drive amplifiers.
– Rough offset adjustment:
If the axis moves even though the nominal value input is clamped to 0 V, the offset
potentiometer must be adjusted such that the axis comes to a stop. After the offset adjustment,
remove the short-circuit bridge on the nominal value input.
– Rough velocity adjustment:
Connect battery supply to the nominal value input. Adjust the battery supply to 9 V and adjust
the drive motor with the tacho-potentiometer to the desired speed (which equals the maximum
rapid traverse rate). The rated speed can be read from the drive motor with a tachometer.
