DIR
Phase output 2, phase B. Open collector output capable of sinking max 500 mA.
Phase output 1, phase B. Open collector output capable of sinking max 500 mA.
Ground and negative supply for both VCC and VSS.
Phase output 1, phase A.
Phase output 2, phase A.
Direction input. Determines in which rotational direction steps will be taken.
77
STEP Stepping pulse. One step is generated for each negative edge of the step signal.
88
ØB Zero current half step position indication output for phase B.
99
ØA Zero current half step position indication output for phase A.
10 10
HSM Half-step mode. Determines whether the motor will be operated in half or full-step
mot. When pulled low, one step pulse will correspond to a half step of the motor.
11 11
INH A high level on the inhibit input turns all phase output off.
12 12
13 13
RC
Bi-level pulse timing pin. Pulse time is approximately ton = 0.55 • RT • CT
LA
Second level (bi-level) output, phase A.
14 14
LB
Second level (bi-level) output, Phase B.
15 15
16 16
VSS
Second level supply voltage, +10 to +40 V.
VCC Logic supply voltage, nominally +5 V.
