Power Stage
A 32-48
MINI
is a stepper motor power stage for bipolar control of 2-phase stepper motors,
which can be plugged-in the minirack.
The precision current control of the power stage A 32-48
MINI
according to the patented
SYNCHROCHOP principle effects optimum running performance of the stepper motor.
The parameters – Run current, Step resolution and Motor direction – can be configured by
rotary switches or ServiceBus.
Step resolution can be set by the rotary switch:
Full step, half step, 1/4, 1/5, 1/8, 1/10 and 1/20 step.
You can program the following step resolutions in ServiceBus mode:
1/1, 1/2, 1/4, 1/5, 1/8, 1/10, 1/16, 1/20, 1/32, 1/64, 1/128, 1/256, 1/512 of a full step.
Motor currents from 0.24 to 3.5 A
Peak
Rotary switch mode:
Run current can be set in 15 steps from 0.15 to 2.00 A
rms
.
ServiceBus mode:
Phase currents can be programmed from 0.10 to 2.50 A
rms
in 10 mA steps.
Inputs
The inputs Control pulse, Motor direction, Boost and Activation are designed for push-pull
controlling. The inputs are optically insulated from the power stage supply voltage by
optocoupler.
Output error
The output error opens in case of short circuit, overcurrent, undervoltage or
overtemperature.
