- xv -Do not touch circuit components until main input power has been turnedOFF. Status indicator LEDs and Digital Operator display will be extinguishedwhen the DC bus voltage is below 50 VDC. Wait 5 additional minutes.Do not connect or disconnect wires and connectors while the main inputpower is turned on.(1) 47P5 drive, with a current rating of 21.0 A and nominal horsepower of 15, is onlyavailable as a V74X drive.The Drive leaves the factory with parameters initialized for 2-Wire control(when using external Run/Stop signals). Before using the initializationfunction of constant n001, know your control wiring configuration:10 = Factory 2-Wire Control Initialization (Maintained RUN Contact)11 = Factory 3-Wire Control Initialization (Momentary START/STOPContact)Entering either Initialization code resets all parameters to factory settings,and automatically returns parameter n001 setting to “ 1 ”. If the Drive isconnected for 3-Wire control and this parameter is set to “ 10 ” (2-WireControl Initialization), the motor may run in reverse direction WITHOUT ARUN COMMAND APPLIED. Equipment damage or personal injury mayresult.WARNINGCAUTIONRated Current Nominal Model NumberInput Voltage Rating [A] Horsepower CIMR-V7* MV0.8 1/8 20P1 A0011.6 1/4 20P2 A0023.0 1/2 20P4 A0035.0 3/4 & 1 20P7 A005230V 8.0 2 21P5 A00811.0 3 22P2 A01117.5 5 23P7 A01725.0 7.5 25P5 A02533.0 10 27P5 A0331.2 1/2 40P2 B0011.8 3/4 40P4 B0023.4 1 & 2 40P7 B003460V 4.8 3 41P5 B0055.5 3 42P2 –8.6 5 43P7 B00914.8 7.5 & 10 45P5 B01521.0 (1) 15 (1) 47P5 (1) –Current Ratings & Horsepower Range
