2 over time. Improper wiring practices could result in drive malfunction due to loose terminal connections. Control Circuit Terminal Block Functions Drive parameters determine which functions apply to the multi-function digital inputs (S1 to S7), multi-function digital outputs (MA, MB), multi-function pulse inputs and outputs (RP, MP) and multi-function photocoupler outputs (P1, P2). The default is called out next to each terminal. Refer to Figure 3.14 on page 69 WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after being wired. Operating a drive with untested control circuits could result in death or serious injury. WARNING! Confirm the drive I/O signals and external sequence before starting test run. Setting parameter A1-06 may change the I/O terminal function automatically from the factory setting. Refer to Application Presets on page 111. Failure to comply may result in death or serious injury. NOTICE: Do not switch an input contactor more often than once every 30 minutes. Improper equipment sequencing could shorten useful life of the drive electrolytic capacitors and circuit relays. Normally the drive I/O should be used to stop and start the motor.

6 Wiring Procedure This section describes the proper procedures and preparations for wiring the terminal board. WARNING! Electrical Shock Hazard. Do not remove covers or touch the circuit boards while the power is on. Failure to comply could result in death or serious injury. NOTICE: Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2, W/T3, -, +1, +2) and other high-power lines. Improper wiring practices could result in drive malfunction due to electrical interference. NOTICE: Separate wiring for digital output terminals MA, MB and from wiring to other control circuit lines. Improper wiring practices could result in drive or equipment malfunction or nuisance trips. NOTICE: Use a class 2 power supply (UL standard) when connecting to the control terminals. Improper application of peripheral devices could result in drive performance degradation due to improper power supply. NOTICE: Insulate shields with tape or shrink tubing to prevent contact with other signal lines and equipment. Improper wiring practices could result in drive or equipment malfunction due to short circuit. NOTICE: Connect the shield of shielded cable to the appropriate ground terminal. Improper equipment grounding could result in drive or equipment malfunction or nuisance trips. Wire the terminal board using Figure 3.18 as a guide (control circuit terminal block). Be sure to prepare the ends of the control circuit wiring as shown in Figure Refer to Wire Gauges and Tightening Torque on page 63 for tightening torque specifications. NOTICE: Do not tighten screws beyond the specified tightening torque. Failure to comply may damage the terminal block. NOTICE: Use shielded twisted-pair cables as indicated to prevent operating faults. Improper wiring practices could result in drive or equipment malfunction due to electrical interference. 74 YASKAWA ELECTRIC TOEP C A YASKAWA AC Drive - PRELIM V1000 Installation & Start-Up Manual
