Multiturn absolute encoder

CSM58

Programmable CAN operating modes

Mode

Explanation

Polled mode

The connected host requests the current actual position value via a remote transmission request telegram. The absolute

encoder reads in the current position, calculates all parameters that have been set and sends back the process actual

value through the same CAN identifier.

Cyclic mode

The absolute encoder sends the current actual process value cyclically, without being prompted by the host. The cycle

time can be programmed in milliseconds for values between 1 ms and 65536 ms.

Sync mode

After the sync telegram has been received by the host, the absolute encoder sends the current actual process value. If

multiple nodes should respond to the sync telegram, the individual nodes report one after the other according to their

CAN identifier. There is no programming of an offset time. The sync counter can be programmed so that the rotary

encoder does not transmit until after a defined number of sync telegrams.

Programmable rotary encoder parameters

Parameter

Explanation

Operating parameter

The direction of rotation (complement) can be specified by parameter as the operating parameter. This

parameter determines the direction of rotation in which the output code will ascend or descend.

Resolution per revolution

The "Resolution" parameter is used to program the rotary encoder so that a desired number of steps can be

implemented in reference to one revolution.

Overall resolution

This parameter indicates the desired number of measurement units of the entire travel length. This value must

not exceed the overall resolution of the absolute encoder.

Preset value

The preset value is the desired position value that must be achieved for a specific physical setting of the axis.

The preset value parameter is used to set the actual position value to the desired actual process value.

2 limit switches

A total of two positions can be programmed. The absolute encoder sets one bit to high state in the 32 Bit

actual process value if a value falls outside the range between these two positions.

8 cam switches

Up to 8 position values can be programmed as cams. By reaching these values bits in object 6300h Cam state

register are set.
