Braking Resistor
|
ERF-150WJ Series
|
To decrease the regenerative energy of the motor and decrease the deceleration time (duty cycle of 3% ED). You must also use the installation attachment.
|
|
Braking Resistor with Fuse
|
CF120-B579 Series
|
To decrease the regenerative energy of the motor and decrease the deceleration time (duty cycle of 3% ED). You must also use the installation attachment.
|
|
Braking Resistor Unit
|
LKEB series
|
To decrease the regenerative energy of the motor and decrease the deceleration time (duty cycle of 10% ED). The unit contains a thermal overload relay.
|
|
Earth Leakage Circuit Breaker (ELCB)
|
NV and NS series
|
To prevent short circuit damage to the power supply system, provide overload protection for wiring, prevent electrical shock, and provide ground fault protection against earth leakage fires.
Note:
-
You can use a molded-case circuit breaker as a replacement for an ELCB that is upstream in the power supply system.
-
When you use a high frequency ELCB at the power input side of the drive, make sure that each drive has a minimum cumulative sensitivity amperage of 30 mA.

|
Molded-Case Circuit Breaker (MCCB)
|
NF series
|
To prevent short circuit damage to the power supply system and provide overload protection for wiring.
|
|
Input Side Magnetic Contactor (MC)
|
SC series
|
To prevent burn damage when connecting a braking resistor. This option fully opens the circuit between the power supply and drive.
|
|
Surge Protective Device
|
200 V class: DCR2-xA
400 V class: RFN3AL-504KD
|
To absorb open/close surges from the magnetic contactor and control relay. You must connect this option to magnetic contactors, control relays, magnetic valves, or magnetic brake coils.
|
|
Zero-Phase Reactor
|
F6045GB
F11080GB
|
To decrease wiring noise. You can use this option on the input side and the output side of the drive.
Note:
Install this option around the drive input power system and as near to the drive as possible.
|
|
Fuse
Fuse Holder
|
CR6L Series
CMS Series
|
To prevent part failure, Yaskawa recommends that you connect a fuse to the input side of the drive.
|
|
Input Side Noise Filter
|
RTEN Series
|
To decrease wiring noise.
Note:
Install this option around the drive input power system and as near to the drive as possible.
|
|
Output Side Noise Filter
|
LF series
|
To decrease wiring noise.
Note:
Install this option around the drive input power system and as near to the drive as possible.
|
|
Capacitor-Type Noise Filter
|
3XYG 1003
|
To decrease wiring noise. You must only use this option around the drive input power system. Do not connect this option to the output side.
|
|
Momentary Power Loss Recovery Unit
|
200 V class: P0010
400 V class: P0020
|
To make sure that the drive has power during the momentary power loss ride-thru time (2 seconds).
|
|
Low-Voltage Manual Load Switch
|
“AICUT” LB series
|
PM motors act as generators when coasting to provide voltage to terminals. Install this option to prevent electric shock.
