R88D-1SN02H-ECT

What is this device used for in a motion system?

It is an AC servo drive for controlling a compatible 1S-series servo motor in position, speed, and torque applications. It is intended for cabinet-mounted industrial motion control where precise, responsive motor control is required.

What motor power rating is it designed for?

It is sized for a maximum applicable motor capacity of 200 W when used with compatible 230 VAC 1S servo motors.

What mains power supply does it require?

The main circuit supply is single-phase 200 to 240 VAC (operating range 170 to 252 VAC), 50/60 Hz (47.5 to 63 Hz). When using a single-phase supply, the supply is connected between any two of the L1, L2, and L3 terminals on the main circuit connector.

Does it need a separate control power supply?

Yes. The control circuit requires 24 VDC (21.6 to 26.4 V). The measured control supply current for this drive class is 600 mA.

Which communication network does it use?

It communicates over EtherCAT and provides IN and OUT ports to support line (daisy-chain) wiring in an EtherCAT network.

How is the EtherCAT node address set?

The node address is set using two rotary ID switches (0 to F in hexadecimal) on the front/top of the drive.

Which motor feedback types can it work with?

It is designed for 1S motors with 23-bit encoder feedback. In the 200 W range, it is used with motors offered with either incremental or absolute encoder variants (for example, the R88M-1M20030H… and R88M-1M20030T… motor types).

What are the key connectors on the drive?

Key connections include: main circuit power/control power/regeneration/DC reactor via the main circuit connector (CNA), motor power output via the motor connector (CNC), motor encoder via the encoder connector (CN2), control I/O via the control I/O connector (CN1), and brake interlock via the brake interlock connector (CN12).

Does it have a built-in regenerative resistor?

No. In the 100 W to 400 W class (which includes 200 W), there is no internal regenerative resistor. If regenerative energy is high, an external regenerative resistor should be connected between B1 and B2. The factory setting has B2 and B3 short-circuited.

Can a DC reactor be added to the drive?

Yes. If a DC reactor is used, remove the short-circuit link and connect the reactor between N1 and N2. If a reactor is not used, N1 and N2 remain shorted.

What are the rated and peak output currents?

For this model, the rated output current is 1.5 Arms and the maximum output current is 5.6 Arms.

What environmental conditions is it specified for?

Ambient operating temperature is 0 to 55°C (storage -20 to 65°C) with up to 90% RH non-condensing. Installation altitude is specified up to 1000 m, and the unit is intended for environments free from corrosive gases.

What is the enclosure rating, and where should it be installed?

The drive itself is rated IP20 and is intended to be built into an appropriate control panel (commonly an IP54 panel or better) as part of a complete system.

What are the approximate physical size and weight?

Typical dimensions are approximately 223 mm (H) × 40 mm (W) × 196 mm (D), with an approximate mass of 1.2 kg for this drive class (R88D-1SN02H-ECT).
