User Manual of EM760 High-Performance Inverter 123 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 ofthe external device via the inverter. Upon receiving an external protection signal, the inverter will display “E4” 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 6.1 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. This terminal will be valid only when F00.06=3~5. Refer to 6.2.1 for details. 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 6.6.11 for details.
28 Speed control/torque control switching These two terminals are used to change the current inverter control mode in conjunction with F13.00 When #28 terminal is valid, speed control and torque control can be switched; and when #29 terminal is valid, only speed control is enabled. See 6.3 for details. 29 Torque control prohibition 30 Motor 1/Motor 2 switching This terminal is used to determine the current valid motor in conjunction with F00.28. If #30 terminal is valid, the motors will be switched based on the F00.28 setting.
31 Resetting of simple PLC status (running from the first segment, with the running time cleared) When this terminal is valid, the simple PLC module will restart running from the first segment. To further understand this function, you can check 6.2.3.2 for instructions.
