Technical data
There are specific modular drives
AXD/MMC
to control synchronous motors (both for feed axis and
spindle applications) and
SPD
to control asynchronous motors (in spindle applications). This chapter is
common to both models because their external characteristics (dimensions, connectors, ...) are the
same.
Note that:
MMC drives have the same currents as AXD drives.
fc
. It represents the switching frequency of the IGBT's.
The dissipated powers correspond to the operation at the rated current in S1 mode.
See the load duty cycle for the modular drives in the corresponding section of this chapter.
