Putting into Operation

Components required:
Basic module 1P 241 (order no.6ES5 241 –lAA11) firmware version A07 or later,
Absolute encoder matching module 4 synchronous–serial
(order no. 6ES5 241 -l AF1l) -1 each per channel
Component set absolute 4 synchronous–serial
(order no. 6ES5 271–lAF1l) – 1 each per channel
External voltage supply 24 V (Connection to the Faston connector on the basic module)
The following settings need to be checked and adjusted if necessary:
Shielding (interference suppression)
Encoder supply voltage (resistor R31)
Sense line on encoder connected or open (see 7.3.5)
Selection of input signal interface (via receiver or opto coupler/switch S2)
Wave resistance R2 for operation via receiver
Code setting for encoder (jumper BR1)
Control bit setting (switches S4 and S1)
Actual value transfer mode to the PLC (switches S5.1 and S5.2)
Presetting the number of clock–pulse groups (TB) via the standard function block or
according to parameterization example

COMMENT TO SWITCH "S5"!
The switches "S5.1" and "S5.2" ARE SCANNED BY THE BASIC MODULE ONLY! The switch posi-
tions inform THE BASIC MODULE ALONE whether the software-based BCD conversion is to be
quick or slow and/or whether no dual (binary) to BCD conversion is to take place at all!
In order to obtain short processing times, it is recommended that you work with the follow-
ing formats:
Actual values Setpoints Jumper BR1 encoder matching module
Gray Code Binary
Binary Binary
This eliminates the conversion times on the basic module
(i.e., no BCD conversion takes place there).
