Okuma Alarm-D 4251 Axis feed rate restriction
under Test-Run Mode: Because there is an Axis, along which Traverse Rate exceeds 2 m/min, it is corrected to 2 m/min.
Code Data bit of Axis, for which Traverse Rate is limited to 2 m/min; in Hexadecimal, up to 2 digits.
Bit 0 – ZA axis : bit 4 – ZB axis
Bit 1 – XA axis : bit 5 – XB axis
Bit 2 – CA axis : bit 6 – CB axis
Bit 3 – WA axis : bit 7 – WB axis
1B->ZA, XA, WA, ZB axes are taking a speed limit.
20->XB axis is taking a speed limit.
1->ZA axis is taking a speed limit.
Probable Faulty Locations
Programmed Traverse Rate F is too large.
Measures to Take
Revise Traverse Rate F.
