User Manual of A90 Series Inverter 142 36 Count clearing This terminal is used to clear the counter that has a counting function. 37 Length counter input (≤250Hz) This is the pulse input terminal that has a length counting function, the input pulse frequency is limited to 250Hz or below, and only one terminal can be set with this function. See the description of the function codes F16.01 to F16.02. 38 High-speed count input (≤100kHz, only valid for X7) This is the pulse input terminal that has a length counting function, and the input pulse frequency is limited to 100kHz or below. It is invalid only for the terminal X7 (that is, only F02.06=38 can be set).
See the description of the function codes F16.01 to F16.02. 39 Length clearing This length clearing terminal has a length counting function. 40 Pulse input (≤ 100 kHz, only valid for X7) This is a pulse signal input terminal, and the input pulse frequency is limited to 100kHz or below. It is valid only for the terminal X7. ★: This is used only to set the equivalent AI percentage instead of other special functions (e.g. counting). When F00.04=5, you need to set F02.06=40 and the set frequency pulse needs to be inputted from the terminal X7. 41 Process PID pause When this terminal is valid, PID adjustment will be stopped, and the output of the process PID module will remain unchanged.
For more information, refer to the description of the function code F09.18. 42 Process PID integral pause When this terminal is valid, the PID integral adjustment will be suspended, but the proportional and differential adjustment of the PID will be still valid. This function is known as integral separation. See the F09.20 description. 43 PID parameter switching If the digital input terminal (F09.11=1) for PID parameter switching is valid, PID parameters will be switched. See the description of the function codes F09.05 to F09.13. 44 PID positive/negative switching When this terminal is valid, the PID positive/negative modes will be switched. See the description of the function code F09.04.
45 Stop and DC braking When a stop command is triggered and the frequency reaches the starting frequency (F04.20) for direct braking during stop, braking will be enabled. The braking time is subject to the longer of the terminal closing time and stop/DC braking time (F04.22). 46 DC braking at stop The stop command is not triggered. When there is a stop command, and the frequency reaches the starting frequency (F04.20) for direct braking during stop, braking will be enabled. The braking time is subject to the longer of the terminal closing time and stop/DC braking time (F04.22).
