SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Minimum: Maximum:
1000 (0) 5000000
The standard parameterizing machine data provided support only linear mea-
suring systems. ROD encoders must be converted by the user, i.e. the distance
traversed by the drive between two (coarse) increments must be entered. Value
0 is automatically entered if MD 5011 bit 4 is set to 0 (no linear measuring sys-
tem). Rotary absolute encoders cannot be implemented until sofware version
HLA 01.01.11 and beyond
Minimum: Maximum:
0000 65535
Number of displayable revolutions of absolute encoder in motor measuring sys-
tem. The value is read-only.
Minimum: Maximum:
0000 65535
Resolution of motor absolute encoder in measuring pulses per revolution. The
value is read-only.
Minimum: Maximum:
0 BFFF
