* The maximum peak current can be applied as all of the following criteria are fulfilled:
1. Duration of one peak doesn’t exceed 10 seconds2. Mounting temperature and ambient temperature within operating range3. Over any period of 90 seconds, the RMS value I RMS,90s of the current does not exceed the allowable continuous current I cont,max. In the example of the current consisting of pulses with I = I peak,max and idle phases of I = 0 between them, the maximum allowable duty cycle would be 11.1% (e.g. 10 seconds of I = I peak,max, followed by 80 seconds of I = 0). In a more general way, this requirement can be written as

The Hardware is protected against over-temperature above 114 °C. Since the software has its own temperature protection object which is set to 100 °C by default, this hardware protection will not be triggered.
Using a PT100 is not recommended. Click here for details about temperature sensors
SOMANET Circulo is available in different versions:
With one additional encoder disk in two positions which is mounted on the motor for position control, velocity control and commutation.
With two additional encoder disks, one mounted on the motor for velocity control (dual loop control) and commutation and one mounted on the joint for position control.
