Optional communication protocols 

include CANopen. The CAN bus is 2.0B 

active (11 and/or 29 bit) and is capable 

of all standard frequencies from 10 kHz 

to 1 MHz. CANopen features include 

node guarding, heartbeat producer, 

SDOs and PDOs. Highlights include 

variable PDO mapping and extended 

node identifi er.

The MDrive34AC Plus

2

 Motion Control 

is available with optional closed loop 

control. This increases functionality by 

adding stall detection, position mainte-

nance and fi nd index mark. 

The closed loop confi guration is added 

via a 512 line (2048 edge) optical 

encoder with index mark, internal to the 

MDrive34AC so there is no increase in 

length. Or, for an expanded choice of 

line counts and resolutions, closed loop 

control is available with an interface 

to a remotely mounted user-supplied 

external encoder.

In addition to encoder options, the 

MDrive34AC Plus

2

 Motion Control has 

the capability of electronic gearing by 

following a rotary or linear axis at an 

electronically controlled ratio, or an 

output clock can be generated fi xed to 

the internal step clock.

A sealed version designed to meet 

IP65 specifi cations is also available. 

The sealed assembly allows the 

MDrive34AC to be used in environ-

ments where exposure to chemical, 

dust and liquids may occur.

Three rotary motor lengths are avail-

able as are linear actuators with long 

life Acme screw**.

In ter face con nec tions are ac com plished 

using standard industrial circular con-

nectors. And connectivity has never 

been easier with options ranging from 

 to 

. 

mOTION CONTROL

The MDrive34AC Plus2 Motion Control 

system of fers de sign ers a cost effec-

tive, full featured programmable motion 

con trol ler in te grat ed with a NEMA 34 high 

torque 1.8° brushless step motor and a 

microstepping driver operating at 120 or 

240 VAC.

Unsurpassed smoothness and perfor-

mance delivered by the MDrive34AC are 

achieved through IMS's advanced 2nd 

generation current control. By applying 

innovative techniques to control current 

fl ow through the motor, resonance is sig-

nifi cantly dampened over the entire speed 

range and audible noise is reduced.

The MDrive34AC accepts a broad input 

voltage range from 95 to 264 VAC, deliv-

ering enhanced performance and speed. 

Oversized input capacitors are used to 

minimize power line surges, reducing 

problems that can occur with long cable 

runs and multiple drive systems. An ex-

tended operating range of –40° to +75°C 

provides long life, trouble free service in 

demanding environments.

 Motion Control 

system adds a versatile array of func tions 

by com bin ing a full featured pro gram -

ma ble mo tion controller with our com pact 

and cost ef fec tive MDrive34AC Micro-

stepping products, adding little cost and 

no increase in size. Stan dard of fer ings 

include up to 8 general pur pose I/O lines 

(sourcing or sinking) that operate to +24 

VDC, one 10 bit analog in put, electronic 

gearing, high speed position capture 

input/trip output, microstep res o lu tions up 

to 51,200 steps per rev o lu tion, 0 to 5 MHz 

step clock rate, and a full fea tured easy-

to-program in struc tion set.
