9.3.4 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, in half-step mode.
Each of the twin channels of this card consists of an IC which combines the conversion of the Step
and Direction inputs into control signals for the output to the stepper motor. These control signals
sequence the current in each of a pair of DMOS (Diffused Metal Oxide Semiconductor) H-bridge
motor drivers.
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 pro-
duce an internally regulated +5.5V (VCC and VDD).
Whilst the stepper motor is stationary, the card switches to half power to minimize power consump-
tion.
The card utilizes the mixed decay feature of the IC to achieve the best sinusoidal motor current
waveform for stepper motors. This decreases current ripple and hence decreases motor heating.
Each channel has a separate dipswitch which enables various circuit functions and are shown in
the following table:

1 Enables Full/Half/Quarter/Eight Step Operation
2 Enables Full/Half/Quarter/Eight Step Operation
3 Half Power Timer Enable
