- 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)

All the protective functions activate internal inhibit. There are two modes

of resetting the amplifier after the cause of the inhibit disappears:

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

present.

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.

- 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.
