2.4.3 General information about MASTERDRIVES
MASTERDRIVES units are available with two different modes of
control:
♦ MC Motion Control
♦ VC Vector Control
The control variant does not influence the internal and external safety
circuitry.
Pulse disconnection by the safety relay which is needed to implement
the STO function is always performed on the power module. This is the
case irrespective of the control variant.
There are various methods of achieving safe pulse suppression
depending on the type of construction.
