Instruction Sheet

1		WARNING
	Please carefully read this instruction thoroughly prior to use the DVP-01HC.
	Make sure that power is OFF before wiring.
	This is an OPEN TYPE PLC. The PLC should be kept in an enclosure away from airborne
	dust, humidity, electric shock risk and vibration. Also, it is equipped with protective methods
	such as some special tools or keys to open the enclosure, in order to prevent hazard to users
	or damage the PLC.
	Do NOT connect the AC main circuit power supply to any of the input/output terminals, or it
	may damage the PLC. Check all the wiring prior to power up.
2		INTRODUCTION

2.1Model Name Explanation and Peripherals

Thank you for choosing DELTA’s PLC DVP series. DVP-01HC high-speed counter input module could accept 200KHz pulse from external counter. It uses instruction FROM/TO to read/write the data in module via EH MPU. There are 33 Controlled Registers (CR, each register is 16-bit) in each module. 32 bits data consists of two continuous CRs and allow executing itself after setting CR.

The different counter modes, such as single-phase mode, two phases mode, 16-bit mode or 32-bit mode, can be designated by CR. The controlled registers are written by instruction TO via MPU. When wiring, connect 24V, A24+, B24+, P24+, D24+, A12+, B12+, A5+, B5+, P5+ and D5+ to positive potential. In the same way, 0V, A24-, B24-, P24-, D24-, A12-, B12-, A5-, B5-, P5- and D5- should be connected to negative potential.

Input signal source could be 1-phase or 2-phase encoder and voltage level could be 5V, 12V and 24V. Besides, it also provides two terminals, PRESET and DISABLE. When terminal “PRE” is on, the data in CR#10 and CR#11 will be sent to CR#20 and CR#21. That also means

2.3Wiring

			1.	Please use O-type or Y-type terminals for I/O wiring terminals. The
Below 6.2				specification for the terminals is as shown on the left. Tighten PLC
				terminal screws to a torque of 5 to 8 kg-cm (4.3~6.9 in-lbs).
		To suit M3.5 screw terminals
			2.	I/O signal wires or power supply should not run through the same
Below 6.2				multi-wire cable or conduit.
			3.	Use copper conductor only, 60℃.

Make sure the positive/negative pole of 01HC input terminal wiring is correct when using NPN encoder.

Start-up current for 01HC is IPEAK=0.8A and general working current is IMAX=0.2A(input voltage is +24V).

Setting notices:

1.It must write with 32-bit.

2.It only can be write-in when writing value is greater or equal to current count value.

3.It only can be set when counter stops counting and count mode is 16-bit.
