Function

Remarks

1a

Output 6

*

1b

Current monitor

This analog output represents the actual current

in the motor. The scale (in A/V) is: Ip / 7.5

Ip - Rated peak current of amplifier.

2a

Output 7

*

2b

Velocity / current mode

selection

When input is left open (low level) the analog

part of the amplifier is working in current mode.

when a high level signal is applied (>2V), the

analog part of the amplifier is working as a high

gain velocity amplifier.

3a

Output 8

*

3b

Motion command (+5V)

This analog output represents the current command

from the position loop to the power amplifier. It

is useful for monitoring the position loop

response.

5b

+5V output

There are several +5V terminals. The accumulative

external load should not exceed 200mA.

7a

Motion Complete

This output will go to high when motion is

complete. *

7b

+15V output

100mA.

8a

Inhibit output

Whenever the amplifier is inhibited, this open

collector output goes low.

8b

-15V output

100mA.
