ES750N Driver Overview
The ES750N series is Inovance’s dual-axis servo drive platform for hydraulic servo applications, supporting 11kW–55kW (T1/T2/T3 chassis). It can drive two permanent-magnet synchronous motors simultaneously (U1V1W1 + U2V2W2), has a built-in pressure-control mode, supports resolvers and 23-bit encoders, and supports EtherCAT and CAN.

Suggested reading path
- First-time installation — Read Electrical Installation & Design first to verify main-circuit, encoder, and communication wiring.
- First-time commissioning — Read the Quick Tuning Guide and follow the steps for parameter reset, motor identification, and pressure-mode setup.
- When alarms occur — Check Troubleshooting to locate the fault code and apply the recommended remedy.
- Mixed-motor commissioning — For the ES680N + ES750N mixed-motor setup, see Mixed-Motor Debug Parameters.
