2. Press the Up Arrow

or Down Arrow key to select the parameter Fn013.

3. Press the DATA/SHIFT key. The following display will appear.

4. Press the MODE/SET key. The display will change as follows, and the absolute

encoder’s multi–turn limit setting operation will be performed.

5. Press the DATA/SHIFT key to return to the auxiliary function mode.

This completes the absolute encoder’s multi-turn limit setting operation. Cycle the
power to the servo amplifier.

Multi-turn Setup Using Serial Command

1. Transmit serial command MLTLIMSET

2. Transmit serial command RES

This completes the absolute encoder’s multi-turn limit setting operation.

Machine Zero-Point Setup

The following parameter is used to set the absolute offset position from the initial
setup position. This offset position will be the new machine zero-point.

Note: 1. Serial command ZSET ±nnnnnnnn automatically sets the current position to ±nnnnnnnn [reference

units]. Pn81D is set accordingly. See 6.5 Serial Command Functions for more details on the ZSET
command.
2. Alarm E16A will occur if Pn81D>| Pn81B, Pn81C| when Pn81A=1, 2, or 3. Refer to 5.2.2 setting
the Overtravel Limit Function.
