EM500 Open-Loop Vector Control Inverter User Manual The range of 700FH is -100.00% to 100.00%. See Table 12-2 for details. For general communication (F10.05=0) upper limit frequency) * F00.18 (upper limit frequency) ” . ★ For F00.17=6, upper limit frequency is “ 700AH (communication setting of ★ For F00.17=7, upper limit frequency is “ 7017H (communication setting of upper limit frequency) ” The range of 700AH is 0.00% to 200%. The range of 7017H is 0.00 to F00.16 (maximum frequency). See Table 12-2 for details. (range: Fdown - Fmax).
F00.18 is the maximum operating frequency after inverter starts and denoted by Fup F00.19 is the minimum operating frequency after inverter starts and denoted by Fdown (range: 0.00 Hz - Fup). 1. Upper limit frequency and lower limit frequency shall be set carefully according to the nameplate parameters and working conditions of the controlled motor. Otherwise, motor, after having worked for a long time at a low frequency, would lose its service life due to overheating. 2. The relationship among maximum frequency, upper limit frequency and lower limit frequency: 0.00 Hz≤Fdown≤Fup≤Fmax≤600.00 Hz. 3.
When the set frequency is lower than F00.19 (lower limit frequency), the running mode of inverter is determined through F15.33. By changing the function code, user may reverse motor rotation direction without changing motor wiring. Its function is the same as the switching of any two terminals of motor (U, V and W) in turning motor rotation direction. 1. After parameter initialization, the running direction of motor will be restored to the original status. 2. After system debugging, this function should be used with caution for occasion where motor is not allowed to be reversed. This function is disabled, if inverter is not allowed to be reversed (for example .21=1). 167 No.
