Yaskawa J1000 Compact Vector Control Drive - Manual (Page 231)

n Drive Short-Circuit Rating
This drive has undergone the UL short-circuit test, which certifies that during a short circuit
in the power supply the current flow will not rise above 31,000 amps maximum at 240 V for
200 V class drives and 480 V for 400 V class drives.
• The MCCB and breaker protection and fuse ratings shall be equal to or greater than the
short-circuit tolerance of the power supply being used.
• Suitable for use on a circuit capable of delivering not more than 31,000 RMS symmetrical
amperes for 240 V in 200 V class drives (up to 480 V for 400 V class drives) motor overload
protection.
u CSA Standards Compliance
Figure C.7 CSA Mark
n CSA for Industrial Control Equipment
The drive is CSA-certified as Industrial Control Equipment Class 3211.
Specifically, the drive is certified to: CAN/CSA C22.2 No. 04-04 and CAN/CSA C22.2 No.
14-05.
u Drive Motor Overload Protection
Set parameter E2-01 (motor rated current) to the appropriate value to enable motor overload
protection. The internal motor overload protection is UL listed and in accordance with the
NEC and CEC.
n E2-01: Motor Rated Current
Setting Range: Model Dependent
Default Setting: Model Dependent
Parameter E2-01 (motor rated current) protects the motor if parameter L1-01 is not set to 0
(default is 1, standard induction motor protection enabled).
