User Manual of EM730 Series Inverter The torque depends on the communication and the like. If the master-slave communication (F10.05=1) is enabled, and the inverter works as the slave (F10.06=0), the actual upper frequency limit is “700FH (master-slave communication setting) * F10.08 (slave receiving proportional coefficient) * F00.18 (upper frequency limit)”, and the 700FH data range is -100.00% to 100.00%, as detailed in Table 12-31. For general communication (F10.05=0): a. F00.17=6 , the actual frequency limit is “700AH (communication setting of the upper frequency limit) * F00.18 (upper frequency limit)”. b.
F00.17=7, the actual frequency limit is “7017H (communication setting of the upper frequency limit)”. (maximum frequency). For details, see Table 12-31 . The 700AH data range is 0.00% to 200.00%, and the 7017H data range is 0.00 to F00.16 F00.18 is the highest frequency allowed after the inverter is started. It is represented by Fup, ranging from Fdown to Fmax; Fdown, ranging from 0.00Hz to Fup. F00.19 is the lowest frequency allowed after the inverter is started. It is represented by 1.
The upper and lower frequency limits should be set carefully according to the nameplate parameters and operating conditions of the actually controlled motor, and the motor should be prevented from long-time operation at the low frequency; otherwise, the motor life may be shortened due to overheat. 2. Relationship of the maximum frequency, upper frequency limit and lower frequency limit: 0.00Hz≤Fdown≤Fup≤Fmax≤600.00Hz; 3. When the set frequency is lower than F00.19 (lower frequency limit), the running mode is dependent on F15.33. The rotation direction of the motor can be changed by modifying this function code instead of motor wiring.
This is equivalent to the change in the rotation direction of the motor by adjusting any two wires of the motor (U, V, W). 162 Function code Function code name Parameter description Unit Default setting Attribute mailing address F00.20 Running direction 0: consistent direction 1: opposite direction 0 ● 0x0014
