CACR-SR20SB1AFY118 YASKAWA

When drive is programmed for auto-restart (n060 = " 1 " – " 10 "), the motor may

restart unexpectedly — personal injury may result.

Description:

• Do not connect or disconnect wiring while the power supply is turned on.

• The internal capacitor remains charged even after the power supply is 

turned OFF. Before servicing, disconnect all power to the drive to prevent 

electric shock. Status indicator LEDs and Digital Operator display will be

extinguished when the DC bus voltage is below 50 VDC. Wait at least 1 minute 

after the power supply is disconnected, and all indicators are OFF.

• Do not perform a withstand voltage test on any part of the unit. This electronic

equipment uses semiconductors and may be damaged by high voltage.

• Do not remove the digital operator or the blank cover unless the power supply is

turned OFF. Never touch a printed circuit boards (PCB) while the power supply is

turned ON.

• The drive is not suitable for circuits capable of delivering more than 18000 RMS 

symmetrical amperes, 250V maximum (200V class units) or, 18000 RMS 

symmetrical amperes, 480V maximum (400V class units).

Know your application before using either Initialization function of n001 . This

parameter must be set to " 0 ", " 1 ", " 2 ", or " 3 " to operate the drive. (See

paragraph 5.23 for additional information.)

8 = Factory 2-Wire Control Initialization (Maintained RUN Contact)

9 = Factory 3-Wire Control Initialization (Momentary START/STOP Contact)

Entering either Initialization code resets all parameters, and automatically returns

n001 setting to " 1 ". If the GPD 506/P5 is connected for 3-Wire control and this

constant is set to " 8 " (2-Wire Control Initialization), the motor may run in reverse

direction WITHOUT A RUN COMMAND APPLIED. Equipment damage or personal

injury may result.

When drive is programmed for auto-restart (n060 = " 1 " – " 10 "), the motor may

restart unexpectedly — personal injury may result.

Parameter n012 must be set to proper motor voltage.
