PROFIBUS ABSOLUTE MULTI-TURN ENCODER, MHK515-PROF RANGE
 MHK15-PROF, standard encoder Ø58mm with Profibus interface:
 Robust and compact conception
 Blind shaft Ø 15 mm – reduction hub available
 Precision ball bearings with sealing joint
 High temperatures performances –40°C … +85°C
 Code disc made of unbreakable and durable plastic
 Mechanical memorization of the number of turns by gears
 Resolution : 13 bits = 8192 steps/turn (max 16 bits)
 Number of turns : 12 bits = 4096 turns (max 14 bits)
 Polarity inversion and short circuit protection

Highly integrated circuit in SMD-technology
MHK515-PROF (connection cap included)
Shaft diameter can be reduced at 12mm, 10mm or 8mm by reduction ring (by inserting them into the hollow shaft)

Red LED Green LED
Status / possible cause
Dark
Dark No power supply
Bright Bright
Encoder is ready for operation but it has not received any configuration data after
power on.
Possible causes: address setting incorrect, Bus lines not connected correctly
Bright Flashing
Parameter or configuration error. The encoder receives configuration or parameter d
a
incorrect length or inconsistent data
Possible cause: parameter value “total measuring range” too high
Flashing Bright
The encoder is ready for operation but not addressed by the master
(e.g. incorrect address in configuration).
Bright Dark
Encoder has not received any data for a longer period (about 40 sec.)
Possible cause: bus line has been interrupted
Dark Bright Normal operation in data exchange mode
Dark Flashing Commissioning mode
