Table 4.6.1: 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.
Please note: 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.
7 Functional description
In figure 7.1 the main parts of the PD86-1180 are shown. The PANdrive™ mainly consists of the µC
(connected to the EEPROM TMCL™ memory), the TMC428 motion controller, the TMC262A-PC power driver
with its energy efficient coolStep™ feature, the external MOSFET driver stage, the QSH8618 stepper motor,
and the integrated sensOstep™ encoder. Alternatively it is possible to connect an external encoder. Nominal
supply voltages are 24VDC or 48VDC.
