Drive enable signal:
The drive will need to be enabled to allow it to control the motor. The source of this enable signal can be defined during the
commissioning wizard and can also be set using the Mint keyword ‘DRIVEENABLEMODE’ which defines if the drive is enabled
via a hardware input only or whether some form of software interlock (e.g. a Mint program or a communications control word) is
also included. If DRIVEENABLEMODE will be set to include a hardware input (other than the STO inputs) then the
DRIVEENABLEINPUT keyword should be used to specify which input channel is used for this function during the
commissioning process (described later). Drives running as intelligent single axis systems (i.e. running a Mint program) and
Real-time Ethernet controlled drives (i.e. EtherCAT or Ethernet Powerlink) do not typically use a dedicated drive enable input
and tend to rely only on the STO inputs for the hardware control of the drive’s power stage.
The OUTPUTACTIVELEVEL keyword should be used to ensure the
specific output channel selected to control the motor brake is configured to be active low. Motor brake control is configured via
drive parameters dedicated to this function (these keywords all start with the text MOTORBRAKE). It’s important to consider
where the 24Vdc supply for the brake will come from. This should be from a separate isolated power supply from that which is
used to supply logical devices such as the drive control card, and other control equipment.
