3.2.2.3 Recommended Control and Signal Wire Sizes
The recommended wire size to connect I/O signals to the terminal strip on the
Regulator board are shown in table 3.6. Recommended terminal tightening torque
is 0.5 Newton-meters (4.5 in-lb). Operator controls can be up to 303 meters (1000
feet) from the GV3000/SE drive.
Table 3.6 – Recommended Terminal Strip Wire Sizes
3.2.2.4 Recommended Motor Lead Lengths
The following motor lead lengths are recommended to reduce line disturbances and
noise. See figure 3.3.
•
For applications using one motor, motor lead length should not exceed 76
meters (250 feet). Note that drives using vector regulation can only be
connected to one motor at a time.
•
For applications with multiple motors, total motor lead length should not exceed
76 meters (250 feet).
When total lead length exceeds 76 meters (250 feet), nuisance trips can occur,
caused by capacitive current flow to ground. Note that these capacitively-coupled
currents should be taken into consideration when working in areas where drives are
running. If the motor lead length must exceed these limits, the addition of output line
reactors or other steps must be taken to correct the problem. See table 3.7 and 3.8.
Note that the motor lead lengths shown in table 3.7 are only guidelines. Your
application may be restricted to shorter lead length due to:
•
the type of wire
•
the placement of wire (for example, in conduit or a cable tray)
•
the type of line reactor
•
the type of motor.
