Onboard
multiple preset speeds |
It
implements up to 16 speeds via the simple PLC function or combination of DI
terminal states. |
||
Onboard PID |
It
realizes process-controlled closed loop control system easily. |
||
Auto voltage regulation (AVR) |
It
can keep constant output voltage automatically when the mains voltage
changes. |
||
Overvoltage/ Overcurrent stall control |
The
current and voltage are limited automatically during the running process so
as to avoid frequent tripping due to overvoltage/overcurrent. |
||
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 CLVC mode. |
||
Individualized
functions |
High performance |
Control
of asynchronous motor and synchronous motor are implemented through the
high-performance current vector control technology. |
|
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. |
||
Rapid
current limit |
It
helps to avoid frequent overcurrent faults of the AC drive. |
||
Virtual
I/Os |
Five
groups of virtual DI/Dos can realize simple logic control. |
||
Timing control |

Four
motors can be switched over via four groups of motor parameters. |
|
Multiple
communication protocols |
It
supports communication via Modbus-RTU, PROFIBUS-DP, CANlink and CANopen. |
||
Motor
overheat protection |
The
optional I/O extension card enables AI3 to receive the motor temperature
sensor input (PT100, PT1000) so as to realize motor overheat protection. |
||
Multiple
encoder types |
It
supports various encoders such as differential encoder, open-collector
encoder, resolver, UVW encoder, and SIN/ COS encoder. |
