III.1 Requirements
The basic parameterization described in Chapter II is finished.

OPMODE :
Set the OPMODE “1,analog speed”
Analog function :
Set the analog I/O-function to “0,Xsetp=An In 1”
Save the parameters :
- Click on the button
- Answer the query RESET AMPLIFIER with YES
An In 1 :
Short-circuit the analog input 1 or apply 0V to it
OSCILLOSCOPE :
Channel1 : n_act
Channel2 : I_act
Reversing mode :
Go to the screen page OSCILLOSCOPE/SERVICE/PARAMETER and set the
parameters for reversing mode to values that are safe for your machine, also when the
positioning control loop is switched off (approx. 10% of the final limit speed).
During operation of the service function “Reversing mode” the analog setpoint input is
switched off and the internal positioning control is disabled.
Make sure that the individual motion of the selected axis is possible without any hazard.
For safety, only operate the ENABLE signal of the amplifier with an interlock switch, and
check the EMERGENCY STOP function for this axis.
III.3 Checking the current controller

If a suitable amplifier-motor combination is used, the current controller will already have
a stable setting for almost all applications.
Ipeak :
- Reduce Ipeak to the Irated value for the motor (protection of the motor)
Switch on the mains/line power.
Provide the analog setpoint :
- An In 1 = 0V
Enable the amplifier :
- High signal at Enable input X3/15. In the AXIS status field: NO SW-EN
- Click on the SW-Enable check box. ENABLE now stands in the AXIS status field.
The motor now stands under speed control, with n=0 rpm. If the current controller is not
stable in operation (motor oscillates with a frequency clearly above 500Hz), please
contact our applications department.
