NOTES FOR FIGURE 1-6
✱
– Indicates components not supplied.
– Main circuit terminal.
– Indicates control circuit terminal.
( ) – Indicates alternate terminal marking, i.e., (R) and L1.
▲
– Function labels shown for these terminals are determined by factory settings of n36
through n39 (see paragraph 5.17).
●
– Function labels shown for these terminals are determined by factory setting of n40
(see paragraph 5.18).
♦
– Function label shown for this terminal is determined by factory setting of n03 (see paragraph 5.11A).
■
– Function labels shown for these terminals are determined by factory setting of n44 (see paragraph 5.16).
1.
Insulated twisted shielded wire is required.
2-conductor #18 GA. (Belden #8760 or equivalent)
3-conductor #18 GA. (Belden #8770 or equivalent)
Connect shield only at drive end (ground terminal ( ) ). Stub and isolate other end.
2.
+12V voltage output current capacity of control terminal FS is 20mA max.
3.
The Drive does not include overload 1OL; it is a separate item. It may not be required; see page 5.34. The contact
from the separately supplied overload relay should be interlocked with the Drive as shown. It should be the manual
reset type to prevent automatic restart following a motor fault and subsequent contact reclosure after cool down. For
Canadian installations, overload 1OL is to be provided in accordance with the Canadian Electrical Code, Part 1 and
NEC.
4.
Customer to connect ground terminal ( ) to earth ground.
5.
If Digital Operator is used, remote operators which duplicate functions of its command keys (see Figure 4-1) may not
be required.
6.
An optional DC reactor may be added for harmonic attenuation, if needed; see separate instruction sheet for wiring.
7.
If application does not allow reverse operation, parameter n05 , Reverse Run Prohibit Selection, should be set to “ 1 ”
(Reverse Run Disabled) and Fwd/Rev input can be eliminated.
CAUTION
Parameter n37 must be set to “ 0 ”, AND parameter
n01 must be set to “ 11 ”. Resetting drive parameter
n01 to “ 10 ” may cause the motor to run in reverse
direction WITHOUT A RUN COMMAND, and possibly
result in equipment damage or personal injury.
