Dual, bipolar recirculating H-bridge, pulse width modulated
switching at 20 kHz. 0.125 - 2.0 amps/phase output current, switch
selectable in 0.125 A increments. 50 watts maximum output power.
Automatic idle current reduction, reduces current to 50% of setting
after one second. Min. motor inductance 1 mH.
HI range: 100 - 12000 steps/sec range, 100 Hz resolution
LO range: 10 - 1200 steps/sec, 10 Hz resolution
Speed adjustable by 15 turn potentiometer, or user supplied
external pot, or 0 - 5 volt analog signal. Linear acceleration and
deceleration, individually adjustable from 750 to 200,000
steps/sec/sec, with single turn potentiometers.
110 or 220 VAC input, switch selectable. 50 - 60 Hz. 75 W max.
DC voltage at nominal line voltage: 28 VDC full load, 40 VDC no
load.
Step: optically isolated, 5-24V, 730 ohm input impedance. Motor
steps on rising edge of step line. 10 µsec minimum low pulse. Step
input used as run/stop in oscillator mode. (closed = run, open =
stop.)
Direction and Enable: optically isolated, 5-24V, 2200 ohm input
impedance. 50 µsec minimum set up time for direction signal.
Optically isolated, uncommitted (open collector, open emitter)
photo transistor. 30V, 20 mA max.

Do I Have the Right Manual?
In April, 1999 we began shipping PDO 2035 drives. Prior to that, we made a similar
drive called the PD2035. The PDO 2035, which is the subject of this manual, sports
the following improvements:
• Connections to the Enable input, the external speed input or the TACH output
used to require a "crimped on" connector, which our customers found to be
complicated and difficult. We now use pluggable, screw terminal connectors for
everything.
• The Step, Dir and Enable inputs now support 5-24V signal levels without adding
dropping resistors or setting the old "5V/24V switch." You can also use sourcing
(PNP) or sinking (NPN) input signals. The PD2035 only accepted sinking signals.
So Which Drive Do I Have?
Just look at the front panel: it either reads "PDO 2035" or "PD2035".
If you have a PD2035, call or fax the factory and request the
"PD2035 User's Manual". You can also download the
manual, in Adobe PDF format, from our website at
