Analog output (drive type: Analog drive connection)
In the "Output" field, select the PLC tag of the analog output over which the drive is to be
controlled. If an output was selected, then it can be configured using the "Device
configuration" button.
In order to be able to select an output, an analog output module must have been added in
the device configuration, and the PLC tag name for the analog output must be defined.
Activate enable output (drive type: Analog drive connection)
In the "Enable output" field, select the PLC tag of the digital output to enable the drive. With
the enable output, the speed controller in the drive is enabled, or disabled.
In order to be able to select an enable output, a digital output module must have been added
in the device configuration, and the PLC tag name for the digital output must be defined.
Note
If you do not use an enable output, the drive cannot be immediately disabled on the part of
the system due to error reactions or monitoring functions. A controlled stop of the drive is not
guaranteed.
Enable ready input (drive type: Analog drive connection)
In the "Ready input" field, select the PLC tag of the digital input with which the drive is to
report its operational readiness to the technology object. The power unit is switched on and
the analog setpoint speed input is enabled.
In order to be able to select a ready input, a digital input module must have been added in
the device configuration, and the PLC tag name for the digital input must be defined.
Note
The enable output and the ready input can be separately enabled.
The following conditions apply to the enabled ready input:
• The axis is not enabled (MC_Power Status=TRUE), until a signal is pending at the ready
• If the signal at the ready input goes away for an enabled axis, then the axis is disabled
• If the axis is disabled with the instruction MC_Power (Enable= FALSE), then the axis is
