Designation / description
_APU_ Display after 1 revolution: Value by
which the display increases/decrea-
ses after 1 revolution of the encoder.
Value range: 0 ... 59 999
_Str_ Encoder pulses per revolution
Value range: 0 ... 59 999
_dP_ Positions after the comma: Determi-
nation of the decimal point position.
Value range: 0. bis 0.000
_drEh Counting direction: Counting direc-
tion of the system.
"I" clockwise increasing values
"E" anti-clockwise increasing values
_Ind_ Reference mark on the encoder disk;
appears only once per revolution.
Used for clear reference point mar-
king.
"0" Signal shape '0'; square signal with
positive logic.
"I" Signal shape 'I'; square signal with
inverted logic.
_rFS_ Reference switch type
"Auto" Automatic referencing when refe-
rence switch and the encoder's index
signal are active (see Kap.10).
"HAnd" Display unit can be referenced at
any position by activating input RFS
(ground switching).
_rEF_ Reference value: can be any value;
value to which the display is reset
after referencing.
Value range: -99 999 ... +99 999
rEL_F Access incremental measuement: To
switch from absolute measurement
and zero-zetting to relative measu-
rement.
"Ein" Incremental measuement on
"AUS" Incremental measuement off
rEF_F Access reference value input enable:
To enter/change reference value (in
input mode).
"Ein" Reference value unlocked
"AUS" Reference value locked
SEt_F Access reset: Press key to set the
display to the reference value (in in-
put mode).
"Ein" Reset function unlocked
"AUS" Reset function locked
_Cntr Control: for service only
9. Input mode
Reset function (to reference value)
Press key to set the display to the reference
value.
Precondition: in programming mode menu point
(SEt_F) must be programmed as 'Ein'. Display MA55
must not be in programming mode (see chapter 7
'To leave programming mode').
Incremental measurement function
For switching on, press the two arrow-keys +
simultaneously.
Display is zeroed.
Decimal point is blinking.
Leave incremental measurement function by ano-
ther press of the keys + ; now the absolute
measuring value is displayed again.
Precondition: in programming mode menu point
(rEL_F) must be programmed as 'Ein'. Display MA55
must not be in programming mode (see chapter 7
'To leave programming mode').
Reference value modification
Press the two keys + simultaneously to enter
a new value.
The display shows the reference value, which can
be changed via the two arrow keys.
Press key to store the new value.
If no key has been pressed for approx. 30 s or if
you press again key , MA55 will return to dis-
play mode.
Precondition: Parameter 'reference value input
enable' (rEF_F) respectively must be programmed
to "Ein" in programming mode. Display MA55 must
not be in programming mode (see chapter 7 'To
leave programming mode').
10. Referencing
The display must always be referenced:
before the first use of the measuring system.
in case of a displacement during power failure.
During reference the counter is set to the pro-
grammed reference value. The display can thus
be zeroed, if reference value were previously pro-
grammed to 0.
10.1 Manual referencing
Manual reference can either be made by:
or by pressing key .
