Device
Description
DC reactor
It is optional for T5 models, and standard for T6 models and
above.
The DC reactor provides the following functions:
● Improves the input‑side power factor.
● Improves the efficiency and thermal stability of the AC
drive.
● Eliminates the impact of high‑order harmonics at the input
side on the AC drive.
● Reduces external conduction and radiation interference
Output reactor
T10 and T12 models with letter L are delivered with an output
reactor.
The output side of the AC drive generally has large high‑order
harmonics. When a motor is far away from the AC drive, much
distributed capacitance exists in the circuit and certain
harmonics may cause resonance in the circuit. This will cause the
following effects:
● Deterioration of motor insulation, damaging the motor in
the long run
● Large leakage current, causing frequent protective trips of
the AC drive.
The output reactor protects motor insulation and reduces
bearing current.
Magnetic ring and
buckle
A magnetic ring on the input side suppresses noise in the input
power supply system of the AC drive. A magnetic ring on the
output side reduces the interference generated by the AC drive to
external devices and reduces the bearing current.
Motor
Select an applicable motor.
External operating
panel
External LED operating panel MDKE10 and LCD operating panel
SOP‑20 are supported.
Note: For selection of peripheral electrical devices, see "Options".
