| Current of braking action: 0.0%~100.0% |
| Automatic rqgulation of voltage (AVR) |
It can keep the output voltage in a state of constant automactically when the grid voltage changes. |
| Function of fast current limiting |
It can decrease the over-current fault on a maximum extent, thus protecting the normal operation of the spindle servo driver. |
| Support for kinds of PG cards |
Differential input PG card; Rotating transformer PG card, open collector |
| Power dip ride through |
The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a short time |
| Overvoltage/overcurrent stall control |
The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to over voltage/over current |
| Torque limit and control |
It can limit the torque automatically and prevent frequent over current tripping during the running process. Torque control can be implemented in the FVC mode. |
| Onboard multiple preset speeds |
It implements up to 16 speeds via the simple PLC function or combination of X terminal states |
| Support motor type |
Asynchronous motor, spindle asynchronous servo motor, asynchronous servo motor |
