Surrounding Environment - Mitsubishi Electric MELSERVO-J3 Series Instruction Manual

5. OPERATION
2) When regenerative option is used over 5kW for 200V class and 3.5kW for 400V class
The lead of built-in regenerative resistor connected to P terminal and C terminal of TE1 terminal
block should not be connected.
The generative brake option should be connected to P terminal and C terminal.
A twisted cable should be used for wiring. (Refer to section 14.2.)
3) When brake unit and power regenerative converter are used over 5kW
The lead of built-in regenerative resistor connected to P terminal and C terminal of TE1 terminal
block should not be connected.
Brake unit, power regenerative converter or power regeneration common converter should be
connected to P terminal and N terminal. (Refer to section 14.3 to 14.5.)
A twisted cable should be used for the wiring over 5m and under 10m to use the brake unit. (Refer
to section 14.3.)
4) The power factor improving DC reactor should be connected P
(Refer to section 14.11.)
(2) I/O signal wiring
(a) The I/O signals should be connected correctly.
Use DO forced output to forcibly turn on/off the pins of the CN6 connector. This function can be used to
perform a wiring check. (Refer to section 7.7.4.) In this case, switch on the control circuit power supply
only.
(b) 24VDC or higher voltage is not applied to the pins of connectors CN6.
(c) SD and DOCOM of connector CN6 are not shorted.

5.1.3 Surrounding environment

(1) Cable routing
(a) The wiring cables are free from excessive force.
(b) The encoder cable should not be used in excess of its flex life. (Refer to section 13.4.)
(c) The connector part of the servo motor should not be strained.
(2) Environment
Signal cables and power cables are not shorted by wire offcuts, metallic dust or the like.
