Set in vfd parameters motor data as follows. Diagram dd6 diagram dd7 m 1 ln e diagram dd8 ln e l1 l2 l3 sc z1 u2 z2 u1 cap.
T1 t2 t3 used for giving 3 phase input to vfd and connecting motor to it and wires coming out of m0 m1 and gnd. Diagram dd5 two speed motors for all other single phase wiring diagrams refer to the manufacturers data on the motor. Main circuit wiring the vfd main circuit terminals shown as below figure. Electromagnetic interference emi can be carried on the ground back to the drive via the ground connection shown above. Do different function on motor operation like jog accedeacc time taking feed back up. A basic vfd system generally consists of an ac motor a controller and an operator interface.
Vfd start stop wiring diagram. Motor develop constant rated torque from low. Vf line comes through rated motor point 230 v 50 hz to maximum point 400 v 87 hz with correct ratio. 1 the vfds three phase ac input terminals rl1 sl2 tl3 the power lines input terminals connect to 3 phase ac power through line protection or leakage protection breaker it does not need to consider the connection of phase sequence. Make sure if you have a bypass function that both the vfd and bypass mode operate the motor in the same direction. Switch on the 3 phase power supply.
Change speed of motor 3 phase 2. Vfd is a short form of variable frequency drive or variable voltage variable frequency drivethe vfds are working based on changing the input frequency and input voltage of the motor we can change the speed of the. Change direction of motor 3. Rated vfd output current not less than motor current in delta connection. Thermal contacts tb white m 1 z2 yellow z1 blue u2 black u1 red bridge l1 and l2 if speed controller sc is not required m 1 ln e. Vfd is shorted for variable frequency drive also known as ac drives and inverters thats used to make an ac motor working in variable speed among other parametersthis is definition used in all topical discussion on this paper.
Vfd for ac motors have been the innovation that has brought the. If the vfd system has bypass there will be an overload device for the bypass circuit but if tripped will also prevent the vfd connect to the motor. It reveals the components of the circuit as simplified forms and also the power as well as signal connections in between the gadgets. Test the vfd without a motor to possibly isolate a problem vhz. Controlling a digital keypad on delta vfd m steps for complete motor control. These are outlined below.
Check connections of l1 l2 l3. When looking at a vfd wiring system there are several aspects that need to be consider due to interaction between various wiring in the system itself. I am here with giving you a vfd start stop wiring diagram for running a vfd through panel board push button and keypad of the vfd it is called hmi.
