User Manual of A90 Series Inverter When the output functions of Y1 and R1 are set to “47: PLC output”, the output result will be controlled by the corresponding bit of F03.31. 0 indicates no output and 1 indicates that there is output. 7.5 Start/Stop Control Parameter Group of F04 Group F04.00=0: direct start The inverter will be started at the starting frequency, following DC braking (no DC braking in the case of F04.04=0) and pre-excitation (no pre-excitation if F04.07 is set to 0). After the starting frequency duration expires, the inverter will run at the set frequency. F04.00=1:
start with speed tracking The inverter is smoothly started from the current rotation frequency of the motor, following the speed tracking (size and direction). In order to ensure the motor torque during the start, please set the appropriate starting frequency. To fully establish the magnetic flux during the motor start, the starting frequency should be maintained for some time. The starting frequency F04.01 is not limited by the lower frequency limit. Before the inverter is started, the motor may be in the status of low-speed running or 161 R1 * Y1 0: no output 1: output Function Function code Default Parameter description Unit Attribute code name setting F04.00 Start-up method 0:
