Input/Output Specifications

INPUTS All inputs are optically isolated
STEP:
minimum pulse width: 200 nanoseconds
maximum input frequency: 2MHz
minimum turn on current: 6.5mA
DIRECTION:
minimum setup time: 200 microseconds
minimum turn on current: 8mA
REMOTE:
minimum turn on current: 3.5mA
When input is activated, drive reduces motor current
by ratio set by R , a resistor connected between
remote
REMOTE and CURRENT, as follows:
R = 13,300 (3750 + R )/(R - R ), where
remote c c s
R = resistor asociated with operating current
c
R = resistor asociated with desired standby current
s
NOTE: for zero current, short REMOTE and CURRENT
GEAR SHIFT:
minimum turn on current: 3.5mA
When input is activated, the drive multiplies each
step pulse it receives by a factor of 8.
FAULT OUTPUT
Optically isolated; open collector/emitter output.
Normally active (output turns off on a fault condition).
To clear fault: cycle power.
maximum collector current: 10mA
