Electrical characteristics SET input
Power supply 10 ... 30 V DC Input active HIGH
Current consumption (no load) max. 30 mA Input type comparator
Reverse polarity protection of the yes Signal level HIGH min. 60 % of +V, max: +V
power supply (+V = power supply) LOW max. 30 % of +V
Short-circuit proof outputs yes 1) Input current < 0,5 mA
e1 compliant acc. to EU guideline 2009/19/EC Min. pulse duration (SET) 10 ms
(pending) (acc. to EN 55025, Input delay 1 ms
ISO 11452 and ISO 7637)
New position data readable after 1 ms
UL approval pending
Internal processing time 200 ms
CE compliant acc. to EMC guideline 2004/108/EC
RoHS guideline 2011/65/EU The encoder can be set to zero at any position by means of a HIGH signal on
the SET input. Other preset values can be factory-programmed. The SET input
has a signal processing time of approx. 1 ms, after which the new position data
SSI interface can be read via SSI or BiSS. Once the SET function has been triggered, the encoder
requires an internal processing time of typ. 200 ms; during this time the power supply
Output driver RS485 transceiver type must not be switched off.
Permissible load / channel max. +/- 30 mA The SET function should be carried out whilst the encoder is at rest.
Signal level HIGH typ 3.8 V
LOW with I Load = 20 mA typ 1.3 V
DIR input
Resolution singleturn 10 ... 14 bit
A HIGH signal switches the direction of rotation from the default cw to ccw.
Absoulte accuracy 2) ±1° This inverted function can also be factory-programmed. If DIR is changed when
Repeat accuracy ±0.2° the device is already switched on, then this will be interpreted as an error. The
status output will switch to LOW.
Number of revolutions (multiturn) max. 24 bit
Code binary or gray Response time (DIR input) 1 ms
SSI clock rate 50 kHz ... 2 MHz
Monoflop time ) 15 µs Power-ON time
Note: If the clock cycle starts within the monoflop time a second data transfer After Power-ON the device requires a time of approx. 150 ms before valid data
begins with the same data. If the clock cycle starts after the monoflop time the can be read. Hot plugging of the encoder should be avoided.
cycle begins with the new values. The update rate is dependent on the clock
speed, data length and monoflop time.
Data refresh rate 2 ms
