Current limit adjustments

- Define the continuous current limit by the instruction:

CLn.m (n.m - current in A)

- Define the peak current limit by the instruction:

PLn.m (n.m - current in A)

-Define the maximum peak current duration by the instruction:

PDn.m (n.m - seconds)

Step 5 - Latch mode of the protective functions

All the protective functions activate internal inhibit. There are two modes of resetting the amplifier after the cause of the inhibit disappears:

Self Restart: (LM0)

The amplifier is inhibited only for the period that the inhibit cause is present.

Latch (LM1)

Each failure latches the Inhibit and the failure message on the display. For restart (after clearing the failure source), reset has to be performed by applying logic 0 at the reset input (H/R-17a,E-J3/21), or by turning the power off and on.

For safety reason it is recommended to use the amplifier in the LATCH MODE - LM1

Step 6 - Connecting the Motor

-Turn off the power.

-Connect the leads of the motor.

-Turn on the power.

For proper operation, the system must have negative feedback. If the motor remains in the same position and returns to the same position when you turn the motor shaft and let go, then the position feedback is negative as required. If the motor runs away you have positive feedback. To correct the feedback, just reverse the encoder leads.
