Technical data

Note!

Note

The option A1 cannot be used for COMPAX 1000SL.

When using option A1 (the absolute value sensor interface), the reference travel (find machine zero) normally required in normal mode after switching on is not required. The reference travel is then only required during start-up. The current read sensor position can be found in Status S12.

Supported absolute value sensors

The following Stegmann - absolute value sensors types are supported:

♦AG100MS/GRAY 4096/4096 or

♦AG626XSR 4096/4096.

♦Supply voltage: 24V ± 10%.

♦Sensing code: grey code, single step.

♦Direction of counting: in clockwise direction when looking at the shaft: rising.

♦Data interface: RS422 /24 bit data format (starting with: MSB).

♦Cycle frequency: 100 kHz.

Enable absolute value sensor input

When using equipped A1 option (if this is not already being executed by HAUSER), the absolute value sensor input is enabled using parameter P206. Meaning:

P206 ="1" absolute value sensor input enabled.

♦Only activate the absolute value sensor input if an absolute value sensor has been connected correctly and physically.

♦Continuous mode is not permitted when the absolute value sensor is active.

Option A1 also contains the HEDA interface.

9.6.3 High resolution SinCos sensor system (S1/S2)

COMPAX uses option S1 to support the high-resolution, optical motor position recording process via the Stegmann SinCos sensor system (as a substitute for the motor position recording via resolver).

SinCos single-turn:Type SRS50 SinCos multi-turn: Type SRM50

A SinCos sensor provides the following improvements.

♦Better concentricity.

♦Position recorded with greater absolute accuracy: Resolver:± 0.25°

SinCos: ± 0.005°

♦Resolution of motor speed:

Resolver:16/12 bit (speed-dependent ; 12 bit at higher speeds)

SinCos: 19 bit over the whole range of motor speeds.

♦Less noise at a higher dynamic level via the motor speed resolution.

•With the SinCos multi-turn you also get economical absolute value sensor function.

4096 motor revolutions detected absolute.
