Outputs
Identifier/data type Value/meaning
dnState
DINT
Status (bit coded)
bits10 Zero crossing active (corresponds to the bXZeroPos output signal)
bits14 Internal limitation for calculation:
The dnYSpeedOut_s and/or dnYSpeedOut_s speed outputs are not
able to follow the change in the resulting dnActXPos_p master posi-
tion. The reference to the master cycle gets lost.
Bit15 Group error (see bit 16 ... 31)
bit16 The master position at the dnXPosIn_p input is outside of the permis-
sible modulo value range of the master measuring system (see
XAxisData input).
bits18 The master measuring system and/or the slave measuring system
(the XAxisData and YAxisData inputs) are not modulo measuring sys-
tems, or the modulo cycle in one of the measuring systems is zero.
bits21 Incorrect input value:
•Error when selecting the offset position: The dnXOffset_p input
exceeds the permissible DINT value range minus the master cycle.
(DINT value range = ±2
31
-1 [increments] ≡ ±32768 [rev])
• Gearbox denominator = "0"
bits23 Error in the measuring system:
• The pointers at the XAxisData and/or YAxisData inputs do not re-
fer to a valid axis data structure.
• If coupling is performed via cycles (C05090 = 1), modulo measu-
ring systems must be specified at the XAxisData and/or
YAxisData inputs.
dnYSpeedOut_s
DINT
Output of the setpoint speed (y speed) as a speed signal
• Scaling: 2
26
≡ 15000 [rpm]
• The signal can be used for direct coupling to the LS_PositionFollower system
block (the PF_dnSpeedAdd1_s input).
• Shifts in the resulting master position (e.g. when switching-off the FB via bEnable
= TRUEFALSE) will not be displayed via this signal. The position reference to the
dnXActPos_p master cycle may get lost!
• If the FB is deactivated (bEnable = FALSE), a value of "0" is output.
• Using the measuring system data at the YAxisData input, the setpoint speed is in-
dicated in the real unit of the machine in C05097.
dnXSpeedOut_s
DINT
Output of the resulting master speed as a speed signal
(The resulting change in the dnXPosIn_p master position and the dnXOffset_p mas-
ter value adjustment is displayed.)
• Scaling: 2
26
≡ 15000 [rpm]
• This signal can be used for the coupling of further slave drives.
• Angular trimming via the dnXOffset_p input will be accounted for in this signal.
• The signal directly results from the differentiation of the resulting dnXActPos_p
master position. Considerable position step changes at dnXActPos_p lead to a li-
mitation of this output. In this case, the signal does not display the position step
change at dnXActPos_p.
• If the FB is deactivated (bEnable = FALSE), the resulting master speed is output as
before.
• Using the measuring system data at the XAxisData input, the resulting master
speed is displayed in the real unit of the master measuring system in C05096.
dnXActPos_p
DINT
Output of the resulting master position in [increments]
•If bEnable = TRUE, the dnXPosIn_p master position offset against the dnXOffset_p
offset value will be output. The output signal is limited to the modulo value range
of the master measuring system (XAxisData).
• If the FB is deactivated (bEnable = FALSE), the resulting master position is output
as before.
• Using the measuring system data at the XAxisData input, the resulting master
position is displayed in the real unit of the master measuring system in C05098.
