Chapter 4 Explanation of Functions 4.2.4 Frequency source setting The frequency source setting function allows you to select the method to input the frequency-setting command. Motor rotation direction is inverted when -10 to 0V is given as frequency command to 02-L terminals. Item Function code Data Description (00) (Valid only when the OPE-SR is used) Use the control provided on the digital operator to set the frequency. 01 Input the frequency-setting command via a control circuit terminal (0-L, OI-L, or O2-L). 02 Use the digital operator (function "F001") or remote operator to set the frequency. Input the frequency-setting command via an RS485 communication 03 terminal. Frequency Input the frequency-setting command from the board connected to source A001 04 optional port 1. setting Input the frequency-setting command from the board connected to 05 optional port 2. 06 Use the SJ-FB to input the frequency-setting command as a pulse train (see 4.2.21) 07 Use the SET-Freq command of the easy sequence function as the frequency-setting command. 10 Use the operation result of the set frequency operation function as the frequency-setting command. (see 4.2.12) 4.2.5 Run command source setting The run command source setting function allows you to select the method to input operation commands (to start and stop the motor). As the operation commands via control circuit terminals, turn the FW signal (for forward operation) or RV signal (for reverse operation) on and off to start and stop the motor, respectively. (Note that the factory setting assigns the FW signal to intelligent input terminal [8].) To switch each intelligent input terminal between a and b contacts, specify each terminal with function "C011" to "C019", and then perform input a/b (NO/NC) selection for each terminal. When using the digital operation for the inverter operation, specify the desired motor operation direction with function "F004", and use the RUN and STOP/RESET keys to start and stop the motor, respectively. If the start commands for both forward and reverse operations are input at the same time, the inverter will assume the input of a stop command. Item Function code Data Description 01 Input the start and stop commands via control circuit terminals (FW and RV). Input the start and stop commands from the digital or 02 Run command remote operator. A002 source setting Input the start and stop commands via RS485 03 communication terminals. 04 Input the start and stop commands from option board 1. 05 Input the start and stop commands from option board 2. Terminal [FW] C019 00 a (NO) contact active state C011 to C018 01 b (NC) contact Note 1: If function "31" (forcible operation) or "51" (forcible-operation terminal) is assigned to an intelligent input terminal, the settings made with functions "A001" and "A002" will be invalidated when the said intelligent input terminal is turned on and those methods to input frequency-setting and operation commands which are specified for the said terminal will be enabled. Note 2: On the remote operator (SRW) being used to operate the inverter, pressing the REMT (remote) key enables you to input both frequency-setting and operation commands from the remote operator. Note3: When the DeviceNet option board (SJ-DN) is used, A002 is not needed to be changed from default because the run command source is automatically set via DeviceNet. (In case it is changed, it is to be set as 01, 02 or 03.) 4 - 8 Related code A001: Frequency source setting Related code A002: Run command source setting C001 to C008: Terminal [1] to [8] functions C019: Terminal [FW] active state F004: Keypad Run key routing
Chapter 4 Explanation of Functions 4.2.6 Stop mode selection The stop mode selection function allows you to select one of two methods of stopping the motor when a stop command is input from the digital operator or via the control circuit terminal block. One is to decelerate the motor according to the specified deceleration time and then stop it; the other is to let the motor run freely until it stops. If a start command is input while the motor is in free-running status, the inverter will restart the motor according to the setting of the restart mode after FRS (b088). (See Section 4.2.47.) Item Function code Data Description Stop mode 00 Normal stopping (stopping after deceleration) b091 selection 01 Free-running until stopping Restart mode after 00 Starting with 0 Hz b088 FRS 01 Starting with matching frequency Restart frequency Starting with 0 Hz if the frequency-matching result is b007 0.00 to 400.0(Hz) threshold less than the set lower limit Retry wait time Time to wait until the restart of the motor after b003 0.3 to 100.(s) before motor restart free-running ends 4.2.7 STOP key enable When the control circuit terminal block is selected as the device to input operation commands, the STOP key enable function allows you to enable or disable the motor-stopping and trip reset functions of the STOP key of the digital operator. Related code b091: Stop mode selection F003/F203/F303: Deceleration (1) time setting, 1st/2nd/3rd motors b003: Retry wait time before motor restart b007: Restart frequency threshold b008: Restart mode after FRS Related code b087: STOP key enable This function is effective only when the digital operator (02) is not specified for the run command source setting (A002) (see Section 4.2.5). If the digital operator (02) is specified for "A002", the motor-stopping and trip reset functions of the STOP key are enabled regardless of this setting (STOP key enable). Function code Data Stop command with STOP key Trip reset command with STOP key 00 Enabled Enabled b087 01 Disabled Disabled 02 Disabled Enabled 4 - 9
