3.11 Braking Resistor
92 YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
◆ Installation
Follow these guidelines when installing braking options.
NOTICE: Connect braking resistors to the drive as shown in the I/O wiring examples.
Improperly wiring braking circuits could result in damage to the drive or equipment.
■
Installation Procedure
1. Disconnect all electrical power to the drive and wait at least five minutes
before servicing the drive and any connected components.
2. Remove drive front cover.
3. Use a voltmeter to verify that voltage is disconnected from incoming power
terminals and that the DC bus no longer holds a charge.
4. Follow the installation instructions of the braking resistor closely and
connect it to the drive as described in this manual.
5. Ensure the resistor unit is mounted on a noncombustible surface. Maintain
minimum side and top clearances according to resistor manufacturer
instructions.
WARNING! Fire Hazard. Do not use improper combustible materials. Failure to comply could
result in death or serious injury by fire. Attach the drive or braking resistors to metal or other
noncombustible material.
6. Connect the resistor unit to the drive and to external control circuitry
according to the following table:
Table 3.14 Wire Size for Remote Mount Resistor Unit
7. Reinstall drive covers and resistor covers, if provided.
Terminals B, P, R1, R2 1, 2 <1>
<1> Power Leads for the Remote Mount Resistor Unit generate high levels of electrical noise; group these signal leads
separately.
Wire Size (AWG) 12-10 18-14
<1>
Wire Type 600 V Ethylene Propylene rubber insulated or equivalent
Terminal Screw M4
