current that will be applied to the motor: SW1 and SW2. Please set them according to the

illustration below.

Step 3: Seing Idle Current

Motor heating and power consumption can also be reduced by lowering the motor current

when it is not moving. e STR will automatically lower the motor current when it is idle to

either 50% or 90% of the running current. e 50% idle current seing will lower the holding

torque to 50%, which is enough to prevent the load from moving in most applications. is

reduces motor heating by 75%. In some applications, such as those supporting a vertical load, it

is necessary to provide a high holding torque. In such cases, the idle current can be set to 90%

as shown below.
