Preliminary Operations Prior to Adjustment

Preliminary Conditions

TSX CAY module(s) installed in PLC.
Axis control application(s) connected to the TSX CAY module(s).
Terminal connected to the PLC by the terminal port or the network.
Configuration and axis control program completed and transferred to the PLC processor.
PLC in RUN. It is advisable to inhibit the movement command application program (by using, for example, a program execution condition bit) in order to facilitate the adjustment operations.

Preliminary Checks

Check the connections.
Check that the movements can occur safely.
Check that the mechanical stops are connected in accordance with safety regulations (they generally act directly on the variable speed controller supply sequence).
Check the direction of the tachymetric dynamo connection.

Adjusting the Variable Speed Controller

The variable speed controller can be adjusted by following the manufacturer’s instructions. To do this, connect up a control box instead of the axis control module.

Adjusting the current loop

Step	Action
1	Modify the maximum current value provided by the variable speed controller to a value accepted by the motor (dissipation switching) and by the mechanics (accelerator torque)
2	Adjust the current loop stability

Adjusting the speed loop

Step	Action
1	Adjust the maximum operating speed Allocate a setpoint to the variable speed controller equal to the Maximum operating voltage (UMAX)
2	Adjust the speed loop gain
3	Adjust the offset

Adjusting current limitation according to speed

Step	Action
1	Reconnect the axis control module when adjustment is complete.
2	Readjust the current loop
