CHAPTER 3

MECHANICAL INSTALLATION

SOLID SHAFT ENCODERS

• Mount the flexible coupling 1 on the encoder shaft;
• fix the encoder to the flange 2 (or to the mounting bell) by means of the screws 3;
• secure the flange 2 to the support (or the mounting bell to the motor);
• mount the flexible coupling 1 on the motor shaft;
• make sure the alignment tolerances of the flexible coupling 1 are respected.

Customary installation

CAUTION

Installation and maintenance operations must be carried out by qualified

personnel only, with power supply disconnected. Shaft and mechanical

components must be in stop.

NOTE

For any information on the mechanical data and the electrical characteris
