Product Description

DM860 P860 Motor Controller

Pulse/IO 2.4-7.2A Open Loop Stepper Motor Driver for 57, 86 Nema23 Nema34 Motor CNC Machine

Mechanical Specifications

Unit: mm [inch]

Electrical Specifications (Tj = 25℃/77℉)

Parameters	Min	Typical	Max	Unit
Output current[PK]	0.5	-	7.2(6.0 RMS)	A
Supply voltage	24	36	75	Vac
Pulse Voltage	4	5	28	Vdc
Logic signal current	7	10	16	mA
Pulse input frequency	0	-	200	KHz
Isolation resistance	500	-	-	MΩ

Heat Elimination

Drive's reliable working temperature should be <70℃(158℉), and motor working temperature should be <80℃(176℉)
Recommended to use automatic idle-current mode (current automatically reduces to 60% when motor stops) to reduce drive and motor heating
Drive must be mounted vertically to maximize heat sink area. Use forced cooling method if necessary.

Pin Assignment and Description

The P860 has two connectors: P1 for control signals and P2 for power and motor connections.

Connector P1 Configurations

Pin Function	Details
PUL+	Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, active at each rising or falling edge (software configurable). In double pulse mode (software configurable), this input represents clockwise (CW) pulse, active both at each high level and low level. 4-28V for PUL-HIGH, 0-0.5V for PUL-LOW. For reliable response, pulse width should be longer than 2.5μs for 200K MAX input frequency or 1μs for 500K MAX input frequency.
PUL-	Complementary signal for PUL+
DIR+	Direction 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. For reliable motion response, DIR signal should be ahead of PUL signal by 2.5μs at least. 4-28V when DIR-HIGH, 0-0.5V when DIR-LOW. Rotation direction is also related to motor-drive wiring match.
DIR-	Complementary signal for 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). Usually left UNCONNECTED (ENABLED).
ENA-	Complementary signal for ENA+

Selecting Active Pulse Edge and Control Signal Mode

The P860 supports PUL/DIR and CW/CCW modes and pulse actives at rising or falling edge. Default setting is PUL/DIR mode and rising edge active (NPN, and PNP control signal is on the contrary).

Connector P2 Configurations

Pin Function	Details
GND	Power Ground
+Vdc	Power supply, 20~80 Vdc, Including voltage fluctuation and EMF voltage.
A+,A-	Motor Phase A
B+,B-	Motor Phase B

Microstep Resolution and Output Current Settings

Microstep resolutions and output current are programmable, with microstep settings from full-step to 102,400 steps/rev and output current from 0.5A to 5.6A. When not in software configured mode, an 8-bit DIP switch is used to configure these settings.

Microstep Resolution Selection

When not in software configured mode, microstep resolution is set by SW5, 6, 7, 8 of the DIP switch:

Microstep	Steps/rev (for 1.8° motor)	SW5	SW6	SW7	SW8
2	400	ON	ON	ON	ON
4	800	OFF	ON	ON	ON
8	1600	ON	OFF	ON	ON
16	3200	OFF	OFF	ON	ON
32	6400	ON	ON	OFF	ON
64	12800	OFF	ON	OFF	ON
128	25600	ON	OFF	OFF	ON
256	51200	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
200	40000	OFF	OFF	OFF	OFF

Current Settings

For a given motor, higher drive current increases torque but also increases motor and drive heating. Output current should be set to prevent overheating during long-term operation. When not in software configured mode, the first three bits (SW1, 2, 3) of the DIP switch are used to set dynamic current.

Peak Current	RMS Current	SW1	SW2	SW3
Default/Software configured		ON	ON	ON
3.08A	2.57A	OFF	ON	ON
3.77A	3.14A	ON	OFF	ON
4.45A	3.71A	OFF	OFF	ON
5.14A	4.28A	ON	ON	OFF
5.83A	4.86A	OFF	ON	OFF
6.52A	5.43A	ON	OFF	OFF
7.20A	6.00A	OFF	OFF	OFF

Note: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under high speed conditions.
