Description
EnableDriveOutput BOOL
-
RON "Enable output" for analog drives
FALSE: disabled
TRUE: enabled
EnableDrive
OutputAddress
UDINT
0 to 65535
RON Byte number for the "enable output"
EnableDrive
OutputBitNumber
UDINT
0 to 7
RON Bit number for the "enabling output"
DriveReadyInput
BOOL
-
RON "Ready input" for analog drives
The analog drive signals its readiness to receive
setpoint speeds.
FALSE: disabled
TRUE: enabled
DriveReady
InputAddress
UDINT
0 to 65535
RON Byte number for the "ready input"
DriveReady
InputBitNumber
UDINT

DriveParameter.
ReferenceSpeed
LREAL
0.0 to 1.0E12
RES Reference value (100%) for the setpoint speed of the
drive (N-set)
The setpoint speed is transmitted in the PROFIdrive
frame as a standardized value from -200% to 200%
of the "ReferenceSpeed".
For setpoint specification via an analog output, the
analog output can be operated in the range from -
117% to 117%, insofar as the drive permits this.
MaxSpeed
LREAL
0.0 to 1.0E12
RES Maximum value for the setpoint speed of the drive
(N-set)
(PROFIdrive: MaxSpeed ≤ 2 × ReferenceSpeed
Analog setpoint: MaxSpeed ≤ 1.17 × Refe
r-
enceSpeed)
