Power stage and network cycle
The MR-JE-100B is a servo amplifier from the MR-JE series, rated for a 3-phase or 1-phase 200 V AC input supply drawing 5.0 A, with a permissible fluctuation window of 170 V AC to 264 V AC at ±5% frequency tolerance. Its output stage delivers 3-phase 170 V AC at 6.0 A using sine-wave PWM current control, and the built-in dynamic brake absorbs the regenerative energy during deceleration — no external resistor needed for most duty cycles. On the motion network side, the amplifier communicates over SSCNET III/H at a cycle time selectable between 0.444 ms and 0.888 ms, which sets the position-loop update rate for the connected servo motor.
Compliance and enclosure
The MR-JE-100B carries a CE Declaration of Conformity covering the Low Voltage Directive (EN 61800-5-1) and EMC Directive (EN 61800-3), plus UL 508C listing — fully documented compliance for panels shipping into North American and European markets.
Control power and physical fit
The interface power supply is a separate 24 V DC ± 10% circuit drawing 0.3 A — this keeps the control electronics live even when the main 200 V bus is off, so the SSCNET III/H network and parameter settings hold during a power-down.
