Step + Pin 1
& Step- Pin 14
A pulse on these inputs causes the motor to advance on the leading
edge of the pulse (see Figure 6). The pulse should be at least 1
µ
s
long. Consult your indexer user guide for instructions on how to
change the output pulse width.
The Step inputs are configured as TTL opto isolated inputs.

Di Pin 2
& Direction- Pin 15
These inputs (pins 2 and 15) control the direction of the motor shaft
rotation. Changing the level of these inputs changes the direction in
which the shaft moves. The logic level at this input needs to be
present for at least 2.5
µ
s before the leading edge of the step pulse
[transition to STEP+ (high) STEP- (low)].
The Direction inputs are configured as TTL opto isolated inputs.
Slow Rate Adjust
(Pin 6)
An external variable resistor (100K Ohm, 10 turn recommended) or a
fixed resistor may be connected between this terminal and "Adjust
Common" (pin 19) to control the slow speed of the internal clock
source. When using external speed controls, turn switch 3 off in
order to isolate the internal potentiometers.
Fast Rate Adjust
(Pin 7)
An external variable resistor (10K Ohm, 10 turn recommended) or
fixed resistor may be connected between this terminal and "Adjust
Common" (pin 19) to control the fast speed of the internal clock
source. When using external speed controls, turn switch 3 off in
order to isolate the internal potentiometers.
Fault
(Pin 9 & 21)
This output is a transistor signal which turns on in the event of a
fault. See Figure 7 for possible external wiring connections.
When a fault occurs, the drive will de-energise. Once the fault has
been cleared the drive may be re-energised by either cycling the
Shutdown signal or by cycling the power to the drive.
