Tension control

Four control modes are included: tension closed-loop speed mode,
linear speed closed-loop speed mode, tension closed-loop torque mode and tension open-loop torque mode

Multi-speed running

Up to 16-speed running can be realized through terminals

Built-in PID

Can easily realize closed-loop process control

Peripheral safety self-test

Common DC busbar function

A common DC bus can be shared by multiple VFDs 

JOG key

The JOG key on the operation panel can be used for jog running

Fast current limiting function

A quick current limiting algorithm is embedded to reduce the probability that an overcurrent fault happens to the VFD

Motor parameter identification

Automatic motor parameter identification

Standardized panel extension cable

A constant voltage output can be maintained in case of grid voltage variations

Communication buses

At least six kinds are supported (Modbus, Profinet, CANopen, Profibus-DP, EtherCAT and Ethernet)

Expansion function

STO

Safe torque off in case of emergency

Inductors

VFDs ≤ 45kW have no integrated inductors

VFDs ≥ 55kW have an integrated DC inductor in the standard configuration

VFDs ≥ 200kW an integrated output AC inductor can be selected as an option.

For all H1-Series devices several types of external inductors are available on request.

Braking Resistor

VFDs ≤ 30kW have an integrated brake-unit in the standard configuration

VFDs 37kW to 132kW an integrated brake-unit can be added as an option.

For all H1-Series devices external break units are available on request.
