7.2.3 Byte 2: Status Bits

Bit 7 Bit 6 Bit 5 Bit 4
1 1 1
IP266 is in Teach-In mode
No reference point
No valid machine data
Job completed; 0 = Job in progress
Bit 0 = 1 The IP is synchronized. This bit is set to "1" if the IP 266 was correctly
synchronized with mode 99.
= 0 This bit is set to "0" on every IP 266 runup (Ident run).
Bit 1: Specified number format
Binary or BCD has been entered in the machine data on the IP 266.
The IP 266 returns the relevant code in bit 1 so that you will be able to
interpret the values for position specifications correctly.
= 1: BCD
= 0: Binary
Bit 2 = 1 The axis is in position. This bit is set when the actual position is within
the standstill or zero-speed monitor's tolerance range (see Sec-
tion 2.5.6).
This bit also goes from 0 to 1 when a dwell time has expired.
