Heat Radiation and Installation

Since the controller and motor generate heat, their heat radiation should be considered carefully.

Generated heat depends on the operating conditions. Determine a heat radiation method according to

the operating conditions.

The controller and motor have a temperature detection sensor (thermistor) at the heat generating

section. As a safety function, the thermistor stops control if the detector temperature reaches:

Controller About

70ºC

Motor About

70ºC

(For details, see 9, “Safety Functions.”)

The controller and motor require heat radiation so that their temperatures will not exceed the above values.

Controller installation methods

The controller can be installed by either Method A or B below.

At installation, put the controller frame in contact with a heat-radiating structure (heat sink or cabinet).

Method A has higher heat radiation efficiency. However, select either method by considering the

operating conditions and cable routing. When installing the controller frame, apply thermal grease or

attach a thermal conductive sheet to the contact surface.

Under some operating conditions, forced air cooling by a fan is necessary. Cool the heat-radiating

structure (heat sink or cabinet) and the controller.

In addition to the output amplifier, which is the main source of heat, the control circuit section (DSP)

generates heat.

Allow as much space as possible around the equipment.

Caution

The controller becomes hot during operation.
