User Manual of EM760 High-Performance Inverter Terminal UP/DOWN: Upon setting the digital input port as the corresponding function (the function code for UP and DOWN is 6 and 7 respectively), control is performed via terminals. When the UP/DOWN terminal is valid, the offset frequency will increase/decrease at the rate ofF12.10 and the final frequency is the set frequency plus offset frequency. (2) When the keyboard UP and terminal DOWN are valid at the sametime, or the keyboard DOWN and terminal UP are valid at the same time, despite of the same acceleration and deceleration rates, the offset frequency will fluctuate because of different valid moments. This is a normal phenomenon.
(3) The UP/DOWN function is valid. When F12.41=0, the UP/DOWN function can reduce the output frequency ofthe inverter to 0 without reversing. When F12.41=1,the UP/DOWN function can reduce the output frequency of the inverter to 0, followed by reverse running of the motor. (4) Select the UP/DOWN function in the corresponding frequency setting mode via F12.45. D0: Set D0 as 1 ifmulti-segment speed is used to set frequency and UP/DOWN speed regulation is to be added. D1: Set D1 as 1 if digital frequency F00.07 is used to set frequency and UP/DOWN speed regulation is to be added. D2: Set D2 as 1 ifanalog is used to set frequency and UP/DOWN speed regulation is to be added. D3:
Set D3 as 1 if high-speed pulse is used to set frequency and UP/DOWN speed regulation is to be added. D4: Set D4 as 1 if communication is used to set frequency and UP/DOWN speed regulation is to be added. D5: Set D5 as 1 if keyboard UP/DOWN is desired for speed regulation. Set D5 as 0 if use of keyboard UP/DOWN is not required. D6: If the main frequency setting has changed, all of the UP key, UP terminal, DOWN key and DOWN terminal don't work, and the offset frequency should be changed accordingly, set D6 as 1. D7: Set D7 as 1 ifall main frequency channels need to use the same UP/DOWN offset frequency.
6.2.3 Selection of auxiliary frequency source As shown below, the current setting channel is determined directly by the function code F00.05 during the setting of the auxiliary frequency source B, and the process PID and simple PLC can be involved in the setting. 84
