(12) Motor rated current (Im100) (Cn-20)
Sets the motor rated current in units of 0 .1A . (The motor rated current is
used in the electronic thermal protector to protect the motor .) (See Table 11) .
Setting of reference current of 30% or
below for constant setting shown in
Table 5 is not effective and the current will be limited to 30% .
(13) Carrier frequency lower limit (CARRIER) (Cn-12)
Sets the lower limit of the inverter's carrier frequency in units of 1Hz .
Although the carrier frequency depends on the output frequency and load,
the minimum carrier frequency is set/here .
Fig . 18 shows the relationship between the carrier frequency and the output
frequency .

(14) Torque compensation gain
(KT)
(Cn-22 )
Sets the torque compensation gain in units of 0 .1 .
Fig . 18 Carrier Frequency and Output Frequency
When the maximum applicable inverter motor has the same capacity as- that of
the motor actually used,
this gain is
1 . When a smaller motor is actually
used, the gain is set to 1 .0 or more .
(15) Overtorque detection level (Cn-23 )
Sets the overtorque detection level in ratio to the reference current
(See
Table 11) for setting constants in units of 1% .
Note the overtorque detection
function differs from the stall during operation function .
(16) Frequency monitor gain (K
F)
(Cn-2 4)
Sets in units of 0.01 the gain of the frequency-meter output that the F-I
monitor (JOGS-C02) outputs . (See Fig . 19) .
