Start-Up IP 266

Possible errors:

1. The drive does not move although "Reference point set" is displayed.

You have accidentally executed a "Set reference point".

2. The drive traverses, but does not reduce its speed at the reference point

switch and does not find the reference point.

The reference point switch is either defective or is an "NC" contact.

3. The drive reduces its speed at the reference point switch, but continues

traversing until it reaches the limit switch. "Reference point deleted" is

displayed on the monitor.

The zero mark of the encoder is not used in the IP 266. You must test the

reference point switch signal and the zero mark signal.

If the reference point exists, the software limit switches are also effective.

Traverse in both directions in mode 1 or 2 and check to see whether the

software limit switches are tripped before the hardware limit switches are

reached.

If necessary, you must shift the coordinates of the software limit switches so

that the drive comes to a standstill before reaching the hardware limit

switches.

Increment mode

Once the coordinate system has been established, you can approach absolute

target positions.

Enter various different target positions in modes 6 and 7 and check to see if

the axis reaches these positions.

Executing automatic programs

Write a short traversing program and transfer it to the module.

Test this program in modes 8 and 9.
