Table 6.1 General operational ratings of the module
*) The controller driver electronics has been tested inside a climate chamber running at full current (5.5A
RMS) for 30min without air convection at 50°C environmental temperature.
The motor might heat up well above 50°C when running at full current without proper cooling. This might
substantially increase the environmental temperature for the electronics. When using the coolStep operation
mode, the actual current might be substantially less than programmed max. current producing and
temperature.
