Referencing status
By setting a new actual value in the machine coordinate system (MCS) with PRESETONS, the
referencing status of the machine axis is not changed.
Requirements
● Encoder type
PRESETONS is only possible with the following encoder types of the active measuring
system:
– MD30240 $MA_ENC_TYPE[<measuring system>] = 0 (simulated encoder)
– MD30240 $MA_ENC_TYPE[<measuring system>] = 1 (raw signal encoder)
● Referencing mode
PRESETONS is only possible with the following referencing mode of the active measuring
system:
– MD34200 $MA_ENC_REFP_MODE[<measuring system>] = 0 (no reference point
– MD34200 $MA_ENC_REFP_MODE[<measuring system>] = 1 (referencing of
Startup
Axis-specific machine data
Actual value setting without loss of the referencing status (PRESETONS) must be set axis-
specifically:
MD30460 $MA_BASE_FUNCTION_MASK, bit 9 = 1
Note
PRESETON deactivated
Activation of the "Actual value setting without loss of the referencing status PRESETONS"
function deactivates the "Actual value setting with loss of the referencing status PRESETON"
function. The options mutually exclude each other.
