User Manual of EM730 Series Inverter 175 19 Acceleration and deceleration time terminal 1 The inverters of this series have four groups of acceleration and deceleration time in total. You can define two function input terminals as acceleration and deceleration time terminals. The current acceleration/deceleration time of the inverter depends on the code combination of these four terminals and settings of related function codes. Details are given in the following table. (0/1: the current function terminal is invalid/valid); or see the function codes F15.03 to F15.13 for details.
20 Acceleration and deceleration time terminal 2 20 19 Acceleration and deceleration time 0 0 The first group (acceleration time: F00.14; deceleration time: F00.15) 0 1 The second group (acceleration time: F15.03; deceleration time: F15.04) 1 0 The third group (acceleration time: F15.05; Deceleration time: F15.06) 1 1 The fourth group (acceleration time: F15.07; Deceleration time: F15.08) 21 Acceleration and deceleration prohibition When the acceleration and deceleration prohibition terminal is valid, the execution of acceleration and deceleration commands will be prohibited, and the output frequency of the inverter will remain unchanged.
The inverter in the overcurrent protection status will run based on the current limit. 22 Operation pause The inverter decelerates to stop, but all running parameters will be kept in the memory, such as PLC and PID parameters. When this terminal is invalid, the inverter will restore the running status before stop. 23 External protection input Using this terminal, you can input the protection signal of the external device, to facilitate protection monitoring and protection of the external device via the inverter. Upon receiving an external protection signal, the inverter will display “E14” and freely stop running.
24 Switching of RUN command to keyboard The current command channel depends on the status of these two terminals and setting of F00.02. The priority is as follows: “24: switching of RUN command to keyboard” > “25: switching of RUN command to communication” > “F00.02: command source option”. Refer to the F00.02 description for details. 25 Switching of RUN command to communication 26 Frequency source switching This terminal is mainly used to switch the frequency sources in conjunction with the function code F00.06. When F00.06=3 to 5, this terminal will be valid. Refer to the F00.06 description. 27 Clearing of regular running time The regular running function is defined by F16.05.
This terminal can be used to clear the running time (reset the remaining time of regular running). Refer to the F16.05
