Dual Stepper Drive
Card
CAUTION
ANTI-STATIC HANDLING.
Standard precautions must be adhered to when
handling electronic cards and configuring and inserting into the enclo-
sures.
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 (A3977SED) 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 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.
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 table below:
