Delta Electronics DVP-01HC User Manual

High-speed Counter

DVP-01HC

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.

2.1 Model 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

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

current value of counter will be changed to be factory setting. When terminal “DIS” is on,

“count” operation is disabled.

 There are two outputs, YH0 and YH1, in hardware input module of DVP-01HC. When counter

value is equal to the setting, the corresponding output point will activate. The transistors of

output points are independent and isolated.

5 TRIAL RUN & TROUBLESHOOTING

 MPU connects to HC extension module

1. Make sure that the power of MPU and extension unit is OFF before wiring.

2. Open extension port of EH MPU and connect to HC extension unit with cable. There is no

connection order for EH MPU to connect extension unit, mix connection is allowed.

3. The power supply of HC extension unit must be external +24VDC power supply.

4. Before power up, check if the load circuit of output points YH0 and YH1 is correct, especially

the circuit between YH0+, YH0- and YH1+, YH1-. There is a Zener Diode that is connected

between YH0+, YH0- and YH1+, YH1- in HC. If the positive/negative pole is wrong, it may

cause unexpected result.

5. Before power up, check if A phase or B phase connects to correct voltage level. (there are

three voltage level: +24, +12V and +5V) If +24V signal connects to +5V input terminal, it may

damage internal circuit.

6. After power up MPU, it will start to detect extension module. If no external +24VDC power is

applied to HC at this time or power is applied after EH MPU completing detecting extension

module, the connection will fail. Therefore, power wiring and power supply timing should be

as following.

 When power supply for HC is +24V_INT: t5＞t3, power is ON and the connection of HC extension unit is normal.

 When power supply for HC is +24V_EXT: Because start time (t2) of external power supply

for HC extension module is unknown, user must make sure that t2+t4＜ t1+t5, otherwise HC extension module cannot be detected by MPU.

7. The maximum special extension modules number for EH MPU connects is 8 special

extension modules. After power is ON, EH will save module codes of connected special

modules in D1320~D1327 in order. The module code of 01HC is H’0120. It indicates

communication is OK when H’0120 is displayed in the corresponding special D register by

using HPP02 or other monitor software.

 Troubleshooting

Judge the errors by the indicators on the front panel. When errors occurred on DVP PLC,

please check:

☼ “POWER” LED

The “POWER” LED at the front of HC extension module will be lit (in green) if the power

is on. If the indicator is not on when power up, please remove the wiring on terminals

+24V. Once the indicator lights after this, it means that the 24V DC power supply of the

PLC is overloaded. Please do not use the DC power supply from the +24V terminals,

but use a DC24V power supply instead.

☼ L.V. LED

The “L.V.” LED at the front of HC extension module will be lit if input voltage is not

enough. The extension module won’t active at this time.
