DESCRIPTION

The MDrive34 Speed Control offers the system designer low cost, intelligent velocity control integrated with a NEMA 34 high torque stepping motor and a +24 to +75 volt microstepping drive.

This product features a digital oscillator for accurate velocity control with an output frequency of up to 100kHz. Output frequency will vary with the signal applied to the speed control inputs.

Speed may be adjusted by a 15-25kHz PWM or one of two 0-5volt input signals, one configurable as 0-20mA or 4-20mA. Of the two available speed inputs, one may be selected using SPEED1/SPEED2 allowing the user to preset two speeds that can be digitally selected. The MDrive34 will then accelerate/decelerate to the new value.

The MDrive34 Speed Control features step clock and direction output signals which may be used to control a second  non-speed control MDrive to follow the speed of the Speed Control unit. This simplifies wiring and controlling machines with large tables or wide conveyors while eliminating drift between motor speeds.

There are two basic modes of operation: bidirectional and unidirectional. By moving the center point, both speed and direction are controlled by the analog speed control input. By setting the center point to zero or the lower end of the potentiometer, only velocity is controlled by the speed control input; direction is controlled by a separate digital input.

MDrive34 configurations include a single shaft rotary motor with optional internal optical encoder or a dual shaft version with control knob, a planetary gearbox, and a long life Acme screw linear actuator. The rotary MDrive34 is also available in three different motor lengths: 24, 31 & 47. Interface connections are accomplished using 12.0" (30.5 cm) flying leads.

The MDrive34 Speed Control has 12 setup parameters, configured using the supplied IMS Analog Speed Control GUI. The setup parameters enable the user to configure all MDrive operational parameters which are stored in nonvolatile memory.

CONFIGURING

The IMS Motor Interface software is an easy to install and use graphical user interface (GUI) for configuring the MDrive34 from a computer parallel/SPI port. Access the GUI via the IMS SPI Interface. Features include:

• Easy installation.

• Automatic communication configuration.

• Will not set out-of-range values.

• Tool-tips display valid range setting for each option.

• Ease of use via single screen
  interface (shown below).

Optional cables are available for ease of connecting and configuring the MDrive34.
