The DM442 is the next generation of digital stepping motor controls. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drives in the markets. Its unique features make the DM442 an ideal solution for applications that require low-speed smoothness. Compared to the DM432C, DM442 can output more current. What’s more, owing to its higher performance DSP, driven motors can achieve much higher speed (above 3000RPM) than that of the DM432C, offering servo-like performances. Electrical Specifications (Tj= 25oC/77oF) Parameters DM442 Min Typical Max Unit Output current 0.5 - 4.2 (3 RMS) A Supply voltage +20 - +40 VDC Logic signal current 7 10 16 mA Pulse input frequency 0 - 200 kHz Isolation resistance 500 - - Mohm Connector P1 Configurations Pin Function Details PUL+ Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling edge active (software configurable); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,active both at high level and low level (software configurable). For reliable response, pulse width should be longer than 7.5?s. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals. PUL- DIR+ DIR signal:In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; in double-pulse mode (software configurable), this signal is counter-clock (CCW) pulse,active both at high level and low level (software configurable). For reliable motion response, DIR signal should be ahead of PUL signal by 5?s at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. Please note that rotation direction is also related to motor-drive wiring match. Exchanging the connection of two wires for a coil to the drive will reverse motion direction. DIR- ENA+ Enable signal: This signal is used for enabling/disabling the drive. High level (NPN control signal, PNP and Differential control signals are on the contrary, namely Low level for enabling.) for enabling the drive and low level for disabling the drive. Usually left UNCONNECTED (ENABLED). ENA- Connector P2 Configurations Pin Function Details +Vdc Power supply, 20~40 VDC, Including voltage fluctuation and EMF voltage. GND Power Ground A+, A- Motor Phase A B+, B- Motor Phase B Selecting Microstep Resolution and Drive Output Current Microstep resolutions and output current are programmable, the former can be set from full-step to 102,400 steps/rev and the latter can be set from 0.5A to 4.2A. However, when it’s not in software configured mode, this drive uses an 8-bit DIP switch to set microstep resolution, and motor operating current, as shown below: Microstep Resolution Selection When it’s not in software configured mode, microstep resolution is set by SW5, 6, 7, 8 of the DIP switch as shown in the following table: Microstep Steps/rev.(for 1.8o motor) SW5 SW6 SW7 SW8 1 to 512 Default/Software configured on on on on 2 400 off on on on 4 800 on off on on 8 1600 off off on on 16 3200 on on off on 32 6400 off on off on 64 12800 on off off on 128 25600 off off off on 5 1000 on on on off 10 2000 off on on off 20 4000 on off on off 25 5000 off off on off 40 8000 on on off off 50 10000 off on off off 100 20000 on off off off 125 25000 off off off off Current Settings When it’s not in software configured mode, the first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current.
