●
Terminals P⊕, C, and NΘ are used to connect optional parts. Do not connect these
terminals to an AC power supply.
●
To protect the main circuit, phase power separate and cover the surface that may
come into contact with the main circuit.
●
Do not allow unwanted objects from entering the wiring part of the terminal block.
●
Do not solder the twisted conductors.
●
The tightening torque may vary with terminals. Tighten terminal screws with the
specified tightening torque. You can use a torque screwdriver, torque ratchet, or
torque wrench to tighten terminal screws.
●
When using an electric screwdriver to tighten terminal screws, set the electric
screwdriver to low speed to prevent damage to the terminal screws.
●
Tighten the terminal screws with an angle not higher than 5°. Failure to comply
may damage the terminal screws.
Control circuit wiring requirements
Observe the requirements in standard UL 508 during wiring.
Cable requirements
Cable dimensions must be compliant with requirements in NEC (National Electric
Code) and CEC (Canadian Electrical Code) Part I and local regulations.
●
Use cables with copper conductors.
●
It is recommended to use indoor PVC cables with a voltage class of 600 V and a
maximum temperature of 75°C in continuous operation under the following
conditions:
■
Ambient temperature: ＜ 40°C
■
Working normally at rated values
If the recommended cable specifications for peripheral devices or optional parts
exceed the applicable cable specification range, contact Inovance.
Cable selection
To comply with UL61800‑5‑1 and CSA C22.2 No. 274‑17, power cables used for SV660P
series servo drives must meet the following requirements:
●
Compliant with NEC and Table 310‑16 of NFPA70
●
Comprised of copper conductors with a rated temperature not lower than 75°C
(167°F)
●
14 AWG or higher
●
With a rated voltage not lower than the rated voltage of the servo drive
It is recommended to use cables compliant with UL758 Style 2517 and Style 2586 as
motor main circuit cables.
