This video covers the installation of an ECM 1.5 kit onto an 1100 M and M+
mill. This video doesn't replace the tormach technical document that came
with your machine. Please read all the warnings, cautions, and tool requirements
before you begin. Power off the machine by pushing in the emergency stop button
on the operators box from the PathPilot interface. Select exit. Turn the main
disconnect switch to off. In the electrical cabinet remove the wire
trough covers. Use a Philips head screwdriver to remove the four screws
securing the ECM board cover and set these aside. On the ECM board, mark the
top white connector to help with reinstallation, then disconnect each.
Disconnect all other cables. Remove the four brass standoffs and remove the
board. Remove the ECM 1.5 board from the electrostatic bag, and then use this bag
for the ECM 1.4 board. To receive a refund payment you must repackage and
return the ECM 1.4 board back to Tormach. Remove the remaining brass standoffs and
discard. Install the first four nylon standoffs in the same location as the
brass ones. Mount the ECM 1.5 board into the electrical cabinet with the four
remaining nylon standoffs. Verify that the logo on the ECM board is upright.
There are two jumpers on the middle of the board. Remove the right jumper and
move it to the top pin. Make the wire connections on connector J1. From left to
right, attach wires 443 through 445 with a small flat bladed screwdriver as
follows. Transfer wire is 402 through 408 from the old J1 connector into the new
connector. When finished, verify the wires are configured
correctly. For the ECM 1.5 board cables to correctly fit in the electrical
cabinet you must first remove several tabs by cutting them off with snips.
Put all the connectors back onto the ECM board.
Verify that the white connector you marked earlier is in the top location.
Install the fuse in the bottom left corner of the board.
Reinstall the protective cover with the four screws. Make the VFD connections.
Turn the latch on the VFD cover with a flat bladed screwdriver, then slide down
and remove the cover, and set it aside. Identify wires 403 and the terminal T41
and terminals T1. Please ensure that the pair of 403 wires are going into T1 and
the single 403 wire is capped off with a supplied ferrule. Use a small flat bladed
screwdriver to connect the following wires from connector J1 to the VFD.
Replace the VFD cover that you set aside earlier. Place all the wires into the
wire troughs, and then replace all the wire trough covers. Close the electrical
cabinet door. Verify the installation. power on the machine. Twist out the
emergency stop button, and press the reset button. Do a test of the access
movement. Jog the machine in each direction and confirm that they move as
expected. Do a test of the spindle movement. Set the RPM to 500 and press
forward, and press stop. And repeat for reverse and confirm that it moves as
expected. If you have any troubles or need any assistance please contact
