Function block library
7-189

SHB9300CRV EN 2.0
7.6.61 Position memory (PSAVE)
One function block (PSAVE1)is available.
Purpose
Storage (mains-failure protected)of positions (master value and/or actual value)and comparison to
the actual values. After mains connection it can be checked whether the master valueposition or the
actual value position have changed. This is however only reasonable when using absolute value
encoders (resolver or sin/cos encoders).

PSAVE1-ON d 1435/1 bin 1434/1 2 HIGH = Comparison of inputs MPOS/ACTPOS with values saved and
difference output
PSAVE1-SAVE d 1435/2 bin 1434/2 2 HIGH =
PSAVE-MPOS ph 1437/1 dec[inc] 1436/1 3 Input for master position
PSAVE-ACTPOS ph 1437/2 dec[inc] 1436/2 3 Input for actual position (e.g. rotor position)
PSAVE-M-HI d - - - HIGH = Input value > than position stored
PSAVE-M-LO d - - - HIGH = Input value < than position stored
PSAVE-ACT-HI d - - - HIGH = Input value > than position stored
PSAVE-ACT-LO d - - - HIGH = Input value < than position stored
PSAVE-M-DIFF ph - - - Position difference = Stored position - input
PSAVE-M-SAVE ph - - - Stored position of master drive
PSAVE-ACT-DIFF ph - - - Position difference = Stored position - input
PSAVE-ACT-SAVE ph - - - Stored position of cam drive
Function
l Store position value
l Compare actual position with values stored
l Output of status signals
7.6.61.1 Store position value
l With PSAVE-SAVE = HIGH data from the inputs PSAVE-MPOS and PSAVE-ACTPOS are
accepted and output at PSAVE-M-SAVEand PSAVE-ACT-SAVE. The reading and writing
process is repeated cyclically (1000
1
s
).
l The input data are stored if a H @ L transition occurs at PSAVE-SAVE, i.e. they are available
even if the controller has been disconnected from the mains.
l When the mains is switched on again, the data are transferred to the user memory and output
at PSAVE-M-SAVE and PSAVE-ACT-SAVE.
