Table 9.20 Main Circuit Option
Model
To improve the drive input power factor.
• To prevent damage to the drive when the power supply capacity is large. You must only use this option
when the power supply capacity is more than 600 kVA.
• To decrease harmonic current.
• To improve the power supply total power factor.
To improve the drive input power factor.
• To prevent damage to the drive when the power supply capacity is large. You must only use this option
when the power supply capacity is more than 600 kVA.
• To decrease harmonic current.
• To improve the power supply total power factor.
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.
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.
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.
Use with a braking resistor unit to decrease motor deceleration times.
To prevent short circuit damage to the power supply system and provide overload protection for wiring.
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.
To prevent burn damage when connecting a braking resistor. This option fully opens the circuit between
the power supply and drive.
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.
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.
To prevent part failure, Yaskawa recommends that you connect a fuse to the input side of the drive.
To decrease wiring noise. Install this option around the drive input power system and as near to the drive
as possible.
This option decreases noise emitted from wiring for the output side of the drive. Install this option around
the drive input power system and as near to the drive as possible.
To decrease wiring noise. This option can also be used with the zero-phase reactor.
Note:
You must only use this option around the drive input power system. Do not connect this option to the
output side.
Table 9.21 Frequency Settings and Monitor Options
Model
To use analog signals from the drive to monitor the output frequency and current.
To use analog signals from the drive to monitor the output voltage.
To use an analog input to set the frequency.
To adjust the frequency scaling.
Use this option with the frequency setting potentiometer.
