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.
