Battery power support
It has a wide power supply voltage specification that allows it to be used with a battery power source. It supports DC24V and DC48V. The operating voltage range is as follows.

* For motors with electromagnetic brakes, it is DC22.8 to 32V.

Optimal current control for energy saving
It is equipped with a servo emulation mode that optimizes the current supplied to the motor according to the load conditions.


Visualization of power supply voltage
The driver’s power supply voltage can be monitored from a host control device.

When the driver’s power supply voltage falls below a preset threshold, it outputs a signal.

Application Examples
When installing in a self-propelled device
Equipment Issues | I want to extend the battery life as much as possible. |

Lightweight design reduces strain on equipment
Reducing the mass of the device itself reduces the power consumption of the wheel drive shaft.

*Weight ranges from 84 to 110g for models other than AZD-KR2D.
When installing in a stationary device
Equipment Issues | You want to install drivers and control systems in separate locations to make the entire device smaller. |
