PG constant Sets the number of PG (pulse
generator or encoder) pulses.
Sets the number of pulses per
motor revolution.

H7-02
Operation selection at
PG open circuit (PGO)
Sets the PG disconnection stop-
ping method.
0: Ramp to stop (Deceleration
stop using deceleration time
1, C1-02.)
1: Coast to stop
2: Fast stop (Emergency stop
using the deceleration time
in C1-09.)
3: Continue operation (To
protect the motor or
machinery, do not normally
make this setting.)

H7-04
Operation selection at
deviation
Sets the stopping method when
a speed deviation (DEV) fault
occurs.
0: Ramp to stop (Deceleration
stop using Deceleration
Time 1, C1-02.)
1: Coast to stop
2: Fast stop (Emergency stop
using the deceleration time
in C1-09.)
3: Continue operation (DEV is
displayed and operation
continued.)

PG rotation 0: Phase A leads with forward
run command. (Phase B
leads with reverse run
command.)

Overspeed detection
level
Sets the overspeed detection
method.
Frequencies above that set for
H7-08 (set as a percentage of
the maximum output fre-
quency) that continue to exceed
this frequency for the time set
in H7-09 are detected as over-
speed faults.
