Dual Stepper Drive Card
CAUTION
ANTI-STATIC HANDLING. STANDARD PRECAUTIONS MUST BE ADHERED TO
WHEN HANDLING ELECTRONIC CARDS AND CONFIGURING AND INSERTING
INTO THE ENCLOSURES.
The dual stepper drive card consists of two identical stepper motor drive
circuits used to drive two stepper motors.
The card is connected to both the +24V SW and +24V US supplies. The
switched (SW) supply is protected by a diode-fuse transient suppressor circuit.
The diode operates over an extremely short time period, enabling the circuit to
absorb voltage spikes without rupturing the fuse (F1 - 4Amp). If a sustained
voltage is experienced above its rating, the fuse ruptures. The +24V US is
used to produce an internally regulated +5.5V (VCC and VDD).
Whilst the stepper motor is stationary, the card switches to half power to
minimize power consumption.
