Parameter No. 0 to 3
Rapid traverses for axes are always programmed in mm/min. If axis IV is programmed as a rotary axis, entry
for rapid traverse is in degrees/min. (each rapid traverse must be adjusted with 9 V at the servo-amplifier input).
Parameter No. 4 to 7
Manual feeds can be limited independent of the rapid traverses in parameters 0 to 3
Display of current feed rate

MANUAL OPERATION
.--7167 7 1 F--F
Parameter 167 determines whether the current feed rate is displayed before or after actuation of the direction
buttons and machine start in the MANUAL OPERATION mode.
If "1" i.e. feed rate display before start, is programmed, the feed rates for manual feed (parameter 4 to 7) must
have the same value or the control moves the axes at the lowest feed rate of the abovementioned parameters.
