(Frequency command)
Maximum frequency (F03/A01)
If F31 = 16 (PID output), J01 = 3 (Dancer control), and J62 = 2 or 3 (Ratio
compensation enabled), the PID output is equivalent to the ratio against the primar
y
reference frequency and may vary within r300% of the frequency. The monito
r
displays the PID output in a converted absolute value. To indicate the value up to
the full-scale of 300%, set F30 data to "33" (%).
 Pulse rate (F33) dedicated to FMP㩷
F33 specifies the number of pulses at which the output of the monitored item selected
reaches 100%, in accordance with the specifications of the counter to be connected.
F40, F41
E16, E17
Torque Limiter 1 (Limiting levels for driving and braking)
Torque Limiter 2 (Limiting levels for driving and braking)
If the inverter’s output torque exceeds the specified levels of the driving torque limiter
(F40/E16) and the braking torque limiter (F41/E17), the inverter controls the output frequency
and limits the output torque for preventing a stall.
Specify the limiting levels at which the torque limiter becomes activated, as the percentage of
the motor rated torque.
To switch the inverter’s output torque limiter between torque limiter 1 (F40/F41) and
torque limiter 2 (E16/E17), use the terminal command TL2/TL1 assigned to a digital
input terminal. (Refer to the descriptions of E01 to E05.)
