3. SIGNALS AND WIRING

3.4 Signals and wiring for base unit

CAUTION

When each unit has become faulty, switch power off on the base unit power side.

Continuous flow of a large current may cause a fire.

Switch power off at detection of an alarm. Otherwise, a regenerative brake

transistor fault or the like may overheat the regenerative brake resistor, causing a

fire.

Fabricate the cables noting the shapes of the CNP1A housing (X type) and CNP1B

housing (Y type).

3.4.1 Connection example of power line circuit

Wire the power supply/main circuit as shown below so that power is shut off and the servo-on command

turned off as soon as an alarm occurs, a servo forced stop is made valid, or a controller forced stop is made

valid. A no-fuse breaker (NFB) must be used with the input cables of the power supply.
