Activate parking
encoder
Request to switch off monitoring of the measuring system and actual
value recording in the drive. It is then possible to remove one encoder
(or motor with encoder) on the machine, without having to change the
drive configuration, or without causing a fault.
NOTE:
Before the encoder is de-parked, an acknowledgement of the
outstanding encoder errors must be carried out (ACKNOWLEDMENT
to the PMU)
WARNING:
Except absolute value encoder P183.1 = xx2x.
Here the parking of the encoder is terminated with error!
(Error code = 1)
Absolute value encoders may never be removed from the frequency
converter while live!

Acknowledge
encoder error
Request to return a encoder error (Gx_ZSW, Bit15) .

Re function 1 - 4 (BIT 0 to BIT3):
The function bits are forwarded to the binectors B910 to B917 (see also
FP172x) for optional functionalities.
G1STW Bit 0 = B910 G2STW Bit 0 = B914
Bit 1 = B911 Bit 1 = B915
Bit 2 = B912 Bit 2 = B916
Bit 3 = B913 Bit 3 = B917
Applies only to flying measurement (configuration of digital input)
