MH75/150/450/1500 – Type I
The factory home position for Type I positioners is located by aligning the homing
pin against the housing, after installing the pin in the faceplate hole. Once Home

follows:
1. Make sure robot(s) is in home position.

2. Using the programming pendant in TEACH MODE, jog the faceplate slowly
until the homing hole aligned with the side of the housing (see Figure 7-7).

the hole in the faceplate. The pin may need to be tapped in with a hammer.
4. Cycle power to the amplifier.
5. Slowly jog the drive assembly until the plastic pin just touches the machine
surface (see Figure 7-8) on the housing. If you go too far the pin will bend,
causing a gap at the other end of the pin. Slowly jog the faceplate in reverse
rotation until the gap closes.
