11. 03- 00~03- 05=【16】Disable PID Function
When an input terminal is set to function【16】and is turned on, PID functions is disabled, if it is turned off ,
PID function is enabled again.
12. 03- 00~03- 05=【17】Reset
When a failure that can be manually reset occurs ,turn on a terminal with function 【17】, the failure will be
reset. (Same function as the Reset button on keypad).
13. 03- 00~03- 05=【18】Auto _ Run Mode
When an input terminal is set to function【18】, the programmable auto- sequencer function is enabled,
Refer to description of parameter group 6.
14. 03- 00~03- 05=【19】Speed Search Stop
When starting, the inverter detects the current speed of the motor, and then accelerates from the
current speed to target speed.
15. 03- 00~03- 05=【20】Energy-saving operation
FAN, PUMP or other high inertia loads need greater starting torque, but once the operational speed is
reached they need much less torque. In this mode the output voltage to the motor is reduced to match
the required torque demand, hence providing a saving in energy.
The output voltage gradually declines as the input is ON. It will gradually increase (to the original
voltage) when the input is OFF.
※
Note: The acceleration and deceleration speed of energy saving operation is the same as the speed
of speed search.
16. 03- 00~03- 05=【21】Reset PID Integral value to Zero
When input is engaged, PID integral value is reset to zero.
17. 03- 00~03- 05=【22】Counter Input
Use any of the multi-function inputs (S1 ~S6) and set the relevant parameter (03-00 ~03-05) to 22.
Count Status can be displayed on the inverter by setting parameter 12-00 =8
18. 03- 00~03- 05=【23】Counter Reset
Counter counts can be reset to 0 at any time by using an external input connected to one of the
multi-function inputs (S1~S6) and by setting the relevant parameter (03-00 ~03-05) to 23.
19. 03- 00~03- 05=【24】PLC Input
When anyone of the extermal terminals S1 to S6 set to 24 and turned on，the PLC program inputs will be
enabled.
20. 03- 02=【25】Pulse Input-Width Measure (S3)
When 03-02=25, S3 is the input port of pulse width measurement functions. Parameters
setting and applying are as the followings:
00-05=7 (Pulsed Speed Control)
03-27= 0.01~0.20KHz (Pulse Input Frequency)
03-28=0.01~9.99 (Inverter Frequency _F= duty cycle * (00-12) *(03-28) Hz，and below the Frequency
Upper limit)
To adjust speed through pulse input duty cycle, set parameters as follows:
00-05=7; 03-02=25; 03-27=pulse input frequency; 03-28=1 (as per actual need)
When pulse input frequency is 200Hz, set 03-27=0.20 (must be correct). Along with the duty cycle of this
200Hz pulse input, inverter frequency is varied.
Example 1:
Pulse input frequency is 200Hz (03-27=0.20), duty cycle is 50%, frequency upper limit is 50Hz
(00-12=50.00), and 03-28=1
Inverter frequency is 50% x 50.00 x 1 = 25.00Hz
