Encoders for direct drives with new mounting solution: Sendix 5873
K黚ler developed an innovative solution for mounting the absolute singleturn encoders on gearless drives (direct drives).
Its great advantage with respect to the mounting versions used until now lies in its easy and fast mounting, thanks to an innovative torque stop.
A Set button allowing a fast start-up and the open absolute BiSS interface - including an incremental SinCos track - are further highlights of these encoders.
This solution offers the manufacturers of gearless lifts new possibilities for reducing notably the assembly work, as well in production as in operation.
- Tapered shaft for a high-accuracy direct coupling to the direct drive
- Singleturn resolution up to max. 17 bits with BiSS or SSI interface
- Optional zero point setting button for an easy start-up
- SinCos incremental track with 2048 pulses/revolution
Sendix Absolute with CANopen Lift interface
The Sendix encoders with CANopen Lift interface are available in singleturn and multiturn versions, with removable bus terminal cover for optimal integration in complex CAN networks or with fixed connections - also directly with a SUB-D connector - for the easiest connection possible to the control.
The CANopen Lift interface (Profile DS 417 V1.1) allows a particularly simple implementation of the lift control with suitable special functions such as:
- Car Position unit
- 2 virtual devices: for the position in absolute measuring steps and the position as absolute displacement information in mm
- Lift number programmable
- Independent setting of the node address in conjunction with the CAN identifiers
- Factor for speed calculation (e.g. measuring wheel circumference)
- Integration time for speed value from 1...32
- 2 working areas with 2 upper and lower limits and the corresponding output states
- Extended error management for position sensing with integrated temperature control
- PDO Mapping of variables in the memory, whether position, speed, acceleration or working area - the user decides, which information is available in real-time.
Moreover, the LED's and the SET button allow easy start-up and diagnosis. Node address and baud rate can be adjusted by means of rotary/DIP switches or through software.
Two devices in one:
Multiturn encoder with additional incremental track. The Sendix absolute CANopen field bus encoders are also available with an additional TTL incremental track.
This allows achieving simultaneously, with one single encoder, positioning via the CAN network and a direct rotary speed feedback via the incremental track. This saves costs and installation space for a second encoder.
The encoder delivers, in parallel with the CANopen output, an additional TTL compatible signal with 2048 pulses per revolution.
For that purpose, the encoder is equipped, in addition to the CANopen output, with a RS 422 interface with the signals A, A/, B, B/.
Incremental and absolute encoders
- Controlling of speed and position
- For monitoring of speed limiters
- Cost-effective incremental standard encoders from Ø 58 mm up to Ø 100 mm for lift drives with geared motors (also available for retrofitting on handwheels).
- Absolute shaft copying / lift car positioning
- Absolute encoders with additional incremental track (2048 ppr.) for simultaneous speed control and positioning with just a single device. Save on installation time and money.
