Default value: All 0
Bit 7 to 5 Configured data blocks can be inhibited via keyswitch by setting these bits
(see also WS 800A description).
Bit 4 to 1 The keyswitch can be used to prevent the entry or modification over the NC
operator panel of the following data by setting the corresponding bit(s):
Bit 4 Zero offset (G54 - G57) fine
Bit 3 R parameters angle of rotation zero offset (G54 - G57) coarse
Bit 2 TO wear (parameters P5 to P7)
Bit 1 TO geometry
Bits 2 and 1 are effective only when the standard display for tool offsets
(P0 ÷ 9) is not modified in any way. When configuring tool offsets, the
keyswitch group (bits 5 to 7) for the data fields (P0 to Pxy) must also be
configured via the NC workstation (WS 800A). Bits 1 and 2 can only be set
together or not at all.
Active: At once
