Drive - dialog: NC Drive
Below the axes, in the tree view, there are some setting dialogs at xxx_Drive on the right side of the System Manager. One of them is the dialog "NC Drive", which is described below:
Type
The type of setpoint output used to the drive is selected here. The following types are supported:
Supported types | Description |
|---|---|
Drive connected to M2400 DAC n | The Beckhoff Lightbus M2400 input/output module is used for setpoint output to the drive. |
Drive connected to KL4XXX / KL2502 | The drive receives its setpoint from a KL4xxx analog output terminal or from a KL2502 PWM terminal |
High/low speed drives | The drive can be controlled with this setting option with a digital output terminal with 2 speeds (e.g. Dahlander motor, frequency converter,..). |
Stepper motor drive | The setpoint specification of this so-called "low cost" stepper motor axis is done via digital output terminals |
DAC of the NC Backplane | A digital/analog converter of the Beckhoff NC Backplane outputs the setpoint to the drive. |
Drive (universally applicable) | Universally applicable drive interface. |
Drive connected to CANopen | The drive receives its setpoint synchronously via the CANopen fieldbus interface (e.g. possible with the FC510x |
Linked to
Here, the terminal (incl. the correct channel of the terminal) or the Mxxxx module of the I/O configuration must be selected, which is electrically connected to the setpoint input of the drive. Only terminals/modules matching the set type are offered for linking.
Linking a universal drive
The type Drive (universally applicable) can be used for output systems that are not listed in the type list. In this case, the output value of the axis must be linked and scaled manually. The link is made directly via the output variables of the axis drive.
The input/output variables of the drive have the following meaning:
nOutData1 - (16 or 32 bit) position value of the axis in increments
nOutData2 - (16 or 32 bit) optional velocity value of the axis in increments
nStatus1 - status byte of the drive
nStatus2..4 - further optional status bytes of the drive
nCtrl1 - control byte of the drive
nCtrl2...4 - further optional control bytes of the drive
