[. . . ] HITACHI INVERTER SJ700-2 SERIES INSTRUCTION MANUAL Read through this Instruction Manual, and keep it handy for future reference. NT204X Introduction Thank you for purchasing the Hitachi SJ700-2 Series Inverter. This Instruction Manual describes how to handle and maintain the Hitachi SJ700 Series Inverter. Read this Instruction Manual carefully before using the inverter, and then keep it handy for those who operate, maintain, and inspect the inverter. Before and during the installation, operation, inspection, and maintenance of the inverter, always refer to this Instruction Manual to obtain the necessary related knowledge, and ensure you understand and follow all safety information, precautions, and operating and handling instructions for the correct use of the inverter. [. . . ] Since every output signal is turned on or off immediately when the relevant condition is satisfied, signal chattering may occur if signal outputs conflict with each other. Use this function to avoid such a problem by holding or delaying specific signal outputs. To use this function, set on-delay and off-delay times for individual output terminals (a total of six terminals, such as intelligent output terminals [11] to [15] and the alarm relay terminal). Output terminal On-delay time Off-delay time 11 C130 C131 12 C132 C133 13 C134 C135 14 C136 C137 15 C138 C139 RY(AL*) C140 C141 Item Output on Output off Function code C130/C132/C134/ C136/C138/C140 C131/C133/C135/ C137/C139/C141 Range of data 0. 0 to 100. 0 (s) 0. 0 to 100. 0 (s) Related code C130: Output 11 on-delay time C131: Output 11 off-delay time C132: Output 12 on-delay time C133: Output 12 off-delay time C134: Output 13 on-delay time C135: Output 13 off-delay time C136: Output 14 on-delay time C137: Output 14 off-delay time C138: Output 15 on-delay time C139: Output 15 off-delay time C140: Output RY on-delay time C141: Output RY off-delay time Description Setting of on Setting of off 4. 2. 79 Input terminal response time Related code C160 to C167: Response time of intelligent input terminals 1 to 8 C168: FW terminal response time - The input terminal response time function allows you to specify a sampling time for each of intelligent input terminals 1 to 8 and the FW terminal. You can use this function effectively to remove noise (e. g. , chattering). - If chattering hinders constant input from an input terminal, increase the response time setting for the input terminal. The response time can be set in a range of about 2 to 400 ms (corresponding to settings of 0 to 200). Item Function code Range of data Description Response time of intelligent C160-C167 0.

C085: Thermistor input tuning Connect the external thermistor to control circuit terminals TH and CM1. Make the functional settings according to the thermistor specifications as described below. When using this function, the wiring distance between the inverter and motor must be 20 m or less. Since the thermistor current is weak, isolate the thermistor wiring to the inverter from other wirings appropriately to prevent the thermistor signal from being affected by the noise caused by other signal currents, including the motor current.

Setting for gain adjustment Note: Specifying "01" for the thermistor for thermal protection control (b098) without an external thermistor connected makes the inverter trip. 4 - 72 Chapter 4 Explanation of Functions 4. 2. 81 FM terminal Related code C027: [FM] siginal selection b081: [FM] terminal analog meter adjustment C030: Digital current monitor reference value C105: [FM] terminal analog meter adjustment You can monitor the inverter output frequency and output current via the FM terminal on the control circuit terminal block. (1) FM siginal selection Select the signal to be output from the FM terminal among those shown below. If you select "03" (digital output frequency), connect a digital frequency counter to the FM terminal. To monitor other output signals, use an analog meter.
