Wire removal Pull the wire while pushing the open/close button all the way down firmly with a flathead screwdriver. 1 Open/close button 2 Flathead screwdriver 3 4 NOTE Pulling out the wire forcefully without pushing the open/close button all the way down may damage the terminal block. Use a small flathead screwdriver (tip thickness: 0.4 mm / tip width: 2.5 mm). 5 If a flathead screwdriver with a narrow tip is used, terminal block may be damaged. Commercially available products (as of October 2020) Product name 6 Screwdriver Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage 7 or injury.
Common terminals of the control circuit (SD, PC, 5, SE) Terminals SD (sink logic), PC (source logic), 5, and SE are common terminals (0 V) for I/O signals. (All common terminals 8 are isolated from each other.) Do not earth (ground) these terminals. Avoid connecting terminal SD (sink logic) with terminal 5, terminal PC (source logic) with terminal 5, and terminal SE with terminal 5. 9 In the sink logic, terminal SD is a common terminal for the contact input terminals (STF, STR, STP (STOP), RH, RM, RL, JOG, RT, MRS, RES, AU, and CS) and the pulse train output terminal (FM *1 ). The open collector circuit is isolated from the internal control circuit by photocoupler.
10 In the source logic, terminal PC is a common terminal for the contact input terminals (STF, STR, STP (STOP), RH, RM, RL, JOG, RT, MRS, RES, AU, CS). The open collector circuit is isolated from the internal control circuit by photocoupler. Terminal 5 is a common terminal for the frequency setting terminals (1, 2, and 4) and the analog output terminals (AM and CA *2 ). It should be protected from external noise using a shielded or twisted cable. Terminal SE is a common terminal for the open collector output terminals (RUN, SU, OL, IPF, and FU). The contact input circuit is isolated from the internal control circuit by photocoupler. *1 Terminal FM is provided in the FM-type inverter.
*2 Terminal CA is provided in the CA-type inverter. Signal inputs by contactless switches The contact input terminals of the inverter (STF, STR, STP (STOP), RH, RM, RL, JOG, RT, MRS, RES, AU, and CS) can be controlled using a transistor instead of a contact switch as follows. +24 V Inverter PC +24 V STF, etc. SD Inverter R STF, etc. External signal input using transistor (sink logic) External signal input using transistor (source logic) 77 2.
