[FM1]/[FM2] output
Function
(Monitor the following)
Meter scale
(Full scale at 100%)
10 Universal AO
Command via communications link
(Refer to the RS-485 Communication
User's Manual.)
20000 as 100%
13 Motor output Motor output (kW) Twice the rated motor output
14 Calibration (+) Full scale output of the meter calibration
This always outputs the full-scale
(100%).
15 PID command (SV) Command value under PID control 100% of the feedback amount
16 PID output (MV)
Output level of the PID controller under
PID control (Frequency command)
Maximum frequency (F03)
17
Positional deviation in
synchronous running
Deviation in angle
0% to 50% to 100%,
representing -180° to 0° to +180° of
the deviation
If F31/F35 = 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 primary reference frequency and may vary within
±
300% of the
frequency. The monitor displays the PID output in a converted absolute value. To indicate the value up to the
full-scale of 300%, set F30/F34 data to "33" (%).
F37 Load Selection/ Auto Torque Boost/ Auto Energy Saving Operation 1
F09 (Torque Boost 1)
H67 (Auto Energy Saving Operation (Mode selection)
F37 specifies V/f pattern, torque boost type, and auto energy saving operation in accordance with the characteristics of the
load.
Specify the torque boost level with F09 in order to assure sufficient starting torque.

(To be selected if a motor may be

If a required "load acceleration toque" is more than 50% of the constant torque, it is recommended to
select the linear V/f pattern (factory default).
• Under the vector control with speed sensor, F37 is used to specify whether the auto energy saving operation is
enabled or disabled. (V/f pattern and torque boost are disabled.)
Data for F37 Operation
0 to 2 Auto energy saving operation OFF
3 to 5 Auto energy saving operation ON
• Under the vector control without speed sensor, both F37 and F09 are disabled. The auto energy saving operation
is also disabled.
