The reference speed comes from a manufacturer-specific special
function.
The reference speed corresponds to the ramp output.
The special function will only be evaluated if 1299 S. Special Function Generator is
not “9-zero”.
If 1299 S. Special Function Generator = “9-
Zero”, the value of the ramp output will
always be used.
Rfg unlock = 0 The last speed will be maintained and used.
Rfg unlock = 1 The ramp function is active and changes according to the reference
value and the ramp.
Bit 6/rfg use ref
Rfg use ref = 0 Reference value “0” is used.
Rfg use ref = 1 The reference value from
Override Target Velocity vl [rpm] 1459 is
used.
Bit 8 HALT
HALT = 0 Execute positioning.
HALT = 1 Stop axis. (The frequency inverter remains enabled in “Operation
If 1299 S. Special Function Generator ≠ “9-Zero”, the reference value from the ramp
output will also be used if bit 4 “rfg enable” = 1, and if bit 4 “rfg enable” = 0, the
