Table 19.2 Manual Handle/Step Multiplication Factor
Note : for Table 19.3:
1. When parameter FOVAB (#6020D,) is set to 1, inputs FV1, FV2, FV4,
FV8, and FV16 become effective when the contacts are open, and Oand 1
in the table for the input state and feed override manual jog speeds are
reversed.
2. The manual jog feed rates can be used as the feed rates for part program
by run execution in the automatic operation modes. For details, refer to
19.2.14 Dry Run (DRN) Input.
3. For the thread-cutting in part program execution in the automatic opera-
tion modes, override is possible only at 100'Yo.

Only when manual handle multiplication factor is 100 pulses/step, the
control can be used by any multiplication. The multiplication factor should
be set parameter #6223.
19.2.7 FEED OVERRIDE/MANUAL JOGGING SPEED
SELECTION (FVI , FV2, FV4, FV8, FV16) INPUT, AND
FEED OVERRIDE CANCEL (OVC) INPUT
(1) These input signals are for specifying override speeds between O
and 200% at 10% intervals on the programmed speeds. In the
man-ual jog mode, these inputs determine the manual jog feed
(2) Feed Override Cancel (OVC) Input
This is the input for fixing the feedrate override at 100%. When
the OVC input contact is closed, the feed rate in part program
execution in the automatic operation modes is locked at the
programed value, irrespective of the override input conditions.
19.2.8 RAPID FEEDRATE OVERRIDE (ROV1 , ROV2,
ROV4) INPUT
These inputs are for overriding the rapid feed rates, i. e., the posi-
tioning speed when executing programs in the automatic operation
modes, and the motion speed in the manual jog mode when the RT
input cantact is closed.
