Welcome to G-TV.
Today I will be showing you How to wire up a Yaskawa V1000 AC Drive.
It is strongly recommended that the wiring of your drive should be done with an experienced
technician to prevent any damage to the unit or operator.
The drive and wires should not be live during the installation process and should be removed
from any power source.
I will start by showing where the three phase power will be plugged in by removing the front
cover that is secured by a screw and then take off the protective cover on the bottom.
The three phase inputs are indicated by the R, S and T or L1, L2 and L3.
I will use these wires to simulate a three phase power source.
The motor can be connected to the right side of the drive at the connections labeled U,
V and W or T1, T2, and T3.
To run my drive in remote operation from an external terminal, I will take a closer look
at the I/O terminals.
Starting from the top, my terminals R+, R-, S+ and S- as well as IG are for connecting
to my communications network.
For this demonstration, I will not be using a communications protocol.
Next to the IG terminal is a dip switch for sinking and sourcing which I will talk about
later.
The next row of terminals has P1, P2 and PC as my photocoupler digital outputs.
The next four terminals of A1, A2, +V and AC are my analog inputs and main speed frequency
reference.
I can install a speed pot using the wiper on either A1 or A2, the second wire on +V
and the third wire on AC for the common.
The next two terminals labeled AM and AC are my analog outputs.
These terminals can be connected to an external monitoring device.
Next to this is a terminal labeled MP.
This is for setting up a pulse train output.
Below this is RP on the third row of terminals and is the pulse train input.
The pulse train input is also wired to the common of my main speed frequency reference
input.
To the left of RP is H1.
This is a safety switch and must be connected to HC.
If no safety circuit is installed, I can place a jumper to close the circuit.
The SC labeled terminal is tied to the sink and source mentioned earlier.
As a source the SC terminal will supply power to the connections made and as a sink it will
work in the opposite with the power flowing into the terminal as a common.
I will keep the dip switch in the sink mode and connect this terminal to one of the switches
contact blocks.
You will notice that my contact blocks are jumped together.
The other ends of the switches are to be wired to S1 through S7.
S1 is for creating a forward run/stop, S2 is for creating a reverse run stop.
This will make forward and reversing two separate switches and must be maintained switches.
S3 is for creating an external fault and can be a momentary pushbutton.
This can be used in place of an E-stop if I am looking to coast the motor to a stop.
It would be the equivalent to removing power from the drive.
S4 serves as a fault reset.
This will clear the drive of any fault once the condition is cleared.
S5 and S6 are for multi-speed functionality.
They are preset speeds that can be changed in parameter H1-05 and H1-06.
The S7 terminal is the jog reference, which can be set in parameter H1-07.
My last three terminals on the right are for setting up a digital output with MA as normally
open, MB as normally closed and MC as the common.
