5.2 b: Application 5.2 b: Application Application parameters configure the source of the frequency reference, the Run command, DC Injection Braking, and other application-related settings. u b1: Mode of Operation n b1-01: Frequency Reference Selection Use parameter b1-01 to select the frequency reference source for the REMOTE mode. Note: 1. If a Run command is input to the drive but the frequency reference entered is 0 or below the minimum frequency, the RUN indicator LED on the digital operator will light and the STOP indicator will flash. 2. Press the LO/RE key to set the drive to LOCAL and use the operator keypad to enter the frequency reference. Setting 0:
Operator Keypad Using this setting, the frequency reference can be input by: • Switching between the multi-speed references in the d1- parameters. • Entering the frequency reference on the operator keypad. Setting 1: Terminals (Analog Input Terminals) Using this setting, an analog frequency reference can be entered from terminal A1 using a 0 to 10 Vdc or a 0/4 to 20 mA signal. Note: The input signal type must be set up by setting DIP switch S1 and adjusting parameter H3-01. Refer to H3-01: Terminal A1 Signal Level Selection on page 98 . Using a 0 to 10 Vdc Voltage Input Signal:
Use a circuit such as the one shown in Figure 5.1 or an external 0 to 10 Vdc voltage source like a PLC analog output and set the input level selection for A1 in parameter H3-01 as desired. Refer to H3-01: Terminal A1 Signal Level Selection on page 98 . Figure 5.1 Setting the Frequency Reference by Voltage Input Using a 0/4 to 20 mA Current Input Signal: Connect input A1 to an external current source such as the one shown in Figure 5.2 . Make sure that switch S1 is set to “I” and set the appropriate signal level by entering 2 (4 to 20 mA) or 3 (0 to 20 mA) into parameter H3-01. 72 SIEP C710606 33A OYMC AC Drive – J1000 User Manual No.
