6.1 Replacing the NZ-Motor
The NZ-motor (refer to figure below) situated at the rear of the cam box is
responsible for controlling the part pickup height. A pickup height offset may be
added for those parts which require higher accuracy such as 0603 resistors. This
pick-up height offset function is only used when a setting is made in the Assembly
Shape Library’s “Offset Z” under the “Process” section.
Any failure of the NZ-axis may result in misspicks when placing very small
components.
Some examples of possible reasons for recalibration are:
- When poor pickup results are observed when using the offset function.
- After replacement of the NZ-motor.

6.1.1 Removing the NZ-Axis Motor
Procedure:
1. Turn OFF the machine power.
2. Disconnect both electrical connections to the motor.
3. Loosen the coupling in order to separate the motor from the NZ-axis.
4. Remove the two (2) mounting bolts holding the motor to the coupling
bracket and remove the motor.
6.1.2 Installing the NZ-Axis Motor
Procedure:
1. Secure the new motor to the machine with the two (2) mounting bolts.
2. Reconnect the two (2) electrical connectors to the motor.
Note: Do not tighten the coupling at this stage.
Notice
Note that as the CP-7 utilizes absolute encoders on all axes, it is no
longer necessary to boot up the machine in Mechacheck mode when
performing motor adjustments.
