How to install and connect KCLY KOC680 series inverter.

IPS Engineering introduces you to the inverter installation and wiring KCLYof  KOC680 series inverters. We show you how to connect a potentiometer used as a frequency reference. Starting, stopping, running forward and backward with the push of a button is extremely simple and guaranteed you can practice right away.

Of course, in addition to this guide of ours, you need to carefully read the safety instructions from the manufacturer before embarking on anything technical.

5: Set via PLC programming

6: Set frequency via function

7: PID control

8: Set frequency via Modbus communication

4 b03.01 =? Select function for input DI1 Usually the value is 1: That is, choose the function for DI1 to run forward
5 b03.02 =?  Function selection for input DI2 Usually the value is 2: That is, choosing the function for DI1 is running backwards
6 b03.03 =? Select function for input DI3 Usually set to value 3: In case of 3-wire control, DI3. input is required
7 b03.13 =? Choice of 2-wire or 3-wire control algorithm 0: 2-wire control type 1

1: 2-wire control type 2

2: 3-wire control type 1

3: 3-wire control type 2

WIRING DIAGRAM OF POTENTIOMETER AND BOTTON

Potentiometer wire: You will use a 3-pin potentiometer with a resistor >5kohm. Looking at the wiring diagram, we connect the 3 pins of the potentiometer respectively according to the +10V, AI1, GND. Remember that the potentiometer resistor must be properly connected to the AI1 pin to work properly. NOTE: Potentiometer, you only need to fight like this to run blind.

Switch locking: You just need to focus on the 4 pins that are DI1, DI2, DI3, COM and we will have different ways of wiring depending on your needs:

  • Case 1: Wiring type 2 wire mode 1

EXPLANATION: As shown in figure k1, k2 represents the contact of the push button. There are rules that work out as follows:

K1 ON, K2 OFF is the inverter running forward

K1 OFF, K2 ON is the inverter running in reverse

K1 OFF, K2 OFF is the inverter to stop

K1 ON, K2 ON is to continue running in the running direction

  • Case 2: Wiring type 2 wire mode 2

EXPLANATION: As shown in figure k1, k2 represents the contact of the push button. There are rules that work out as follows:

K1 ON, K2 OFF is the inverter running forward

K1 ON, K2 ON is the inverter running in reverse

K1 OFF, K2 OFF is the inverter to stop

K1 OFF, K2 ON is the inverter to stop

  • Case 3: Wiring type 3 wire mode 1

EXPLAIN: When lock SB1 is closed, push button SB2 to run the inverter, contact SB3 opens for inverter to run forward, SB3 closes for inverter to run in reverse. When button SB1 opens, the inverter will stop.

NOTE: During running and booting, SB1 should always be kept closed

  • Case 4: Wiring type 3 wire mode 2

EXPLAIN: When the SB1 lock is closed, press the SB2 button to run the inverter, the SB3 contact opens for the inverter to run forward, when the SB3 button is closed, the inverter runs in reverse. When button SB1 opens, the inverter will stop.

NOTE: During run and start up, SB1 must remain closed at all times. Buttons SB2 and SB3 cannot be closed at the same time.

HOW TO OPERATE TO CHANGE PARAMETERS

PRACTICAL EXPERIENCE:

PRESENTATIVE SELECTION: Depending on the application need to fine-tune the speed with high or low accuracy. If precision is not required, use a 1-turn potentiometer. More precisely, use the 5-round type. For the very precise type, use the 10-round type.

Acceleration and deceleration time: Depending on the application, the time required for acceleration and deceleration is different. For simple, unfussy applications, always leave the default value. For loads with a large moment of inertia, let the acceleration time be high to avoid overloading.

WIRING EXPERIENCE: The above has 4 ways of wiring, but in fact if the application only runs in one direction, we only need to care about DI1 or DI2 with COM pins and the default setting value is ok. Very convenient and fast without having to worry about many things.
