Built-in one standard encoder feedback interface, support another external optional encoder feedback card.


Built-in four 0-10V analog inputs and two 0-10V analog outputs; By expansion card, can achieve two 0-20mA (or 4-20mA) analog input channels, and two 0-20mA (or4-20mA) analog output channels.

Relay output

2 groups of expansive relay output, each include 1 NC and 1NO contact. Electrical specification:  AC250V/2.5ADC24V/5A

External 24V control power

When main power supply is disconnected to AC800, customer can input an external 24V control power supply to M1 terminal to power on AC800 control board and LCD panel. After control parameters are set and tested correctly, switch the main power on and run the motor. This is more convenient and safe for customers. However, our standard version has no this function. If this function is required, need optional expansion board. Refer to F2,7.

Safe torque off (STO)

Through expansion boards, AC800 can have 2 separated STO control channels in hardware circuits. Any one is not shielded, torque is safely turned off. The STO function is implemented in hardware; it overrides all software activities. The only software involvement is to report STO status to user via an MMI, series interface or user terminal on the AC800 STO expansion board. Refer to F2.7.

Active front end


Detect synchronous signal AFE function need. AT AC800 AFE control mode, can achieve a PWM rectifier or a grid tie inverter with nearly 1.0 power factor and input perfect non-harmonic sine current.
