Precautions For Ce Low Voltage Directive Compliance; Precautions For Ul/Cul Standards Compliance; General Application Precautions - YASKAWA L1000V Technical Manual

Do not lift the drive up while the cover is removed.
This can damage the terminal board and other components.
Do not expose the drive to halogen group disinfectants.
Failure to comply may cause damage to the electrical components in the drive.
Do not pack the drive in wooden materials that have been fumigated or sterilized.
Do not sterilize the entire package after the product is packed.
u Precautions for CE Low Voltage Directive Compliance
This drive has been tested according to European standard EN61800-5-1, and it fully complies with the Low Voltage
Directive. The following conditions must be met to maintain compliance when combining this drive with other devices:
• Do not use drives in areas with pollution higher than severity 2 and overvoltage category 3 in accordance with IEC664.
• Ground the neutral point of the main power supply for 400 V Class drives.
u Precautions for UL/cUL Standards Compliance
This drive is tested in accordance with UL standard UL508C and complies with UL requirements. The following
conditions must be met to maintain compliance when using this drive in combination with other equipment:
• Do not install the drive to an area greater than pollution severity 2 (UL standard)
• Use UL-listed copper wires (rated at 75°C) and closed-loop connectors or CSA-certified ring connectors.
• Wire low voltage wires with NEC Class 1 circuit conductors. Refer to national, state, or local codes for wiring. Use a
class 2 (UL regulations) power supply for the control circuit terminal.
• 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 30,000 amps maximum at 240 V for 200 V class drives and 480 V for 400 V class
drives.
• The drive internal motor overload protection is UL listed and in accordance with the NEC and CEC. The setup can be
done using the parameters L1-01/02.
u General Application Precautions
n
Motor Selection
Drive Capacity
The output current should not exceed 165% of the drive rated current. Select a drive that can output enough current when
accelerating a load at 100%.
For specialized motors, make sure that the motor rated current is less than the rated output current for the drive.
Starting Torque
The startup and acceleration characteristics of the motor are restricted to the drive's overload current rating (165% rated
current for 30 s).
The overload rating for the drive determines the starting and accelerating characteristics of the motor. Expect lower
torque than when running from line power. To get more starting torque, use a larger drive or increase both the motor and
drive capacity.
n
Stopping
Emergency Stop
When the drive faults out, a protective circuit is activated and drive output is shut off. This, however, does not stop the
motor immediately. Some type of mechanical brake may be needed if it is necessary to halt the motor faster than the Fast
Stop function is able to.
