Installation/Wiring

F232120

Table 17 contains the correct display value for each

function.

The first digit in the Input Status parameter does not

correspond to a control input function. Refer to

Table 17.

NOTE: The Preset Speed logic is specific to the type

of computer the machine is equipped with (i.e.,

WE-6 or V-Control).

Balance Output

The Balance Output is transmitted to the machine

controller by the closure of a normally open

mechanical relay shown in Figure 17. This action

occurs at distribution speed connecting TB2-9 and

TB2-10 when the drive detects an acceptable balance

condition.

A secondary out-of-balance switch has been added to

some machine models to prevent an extreme out-of-

balance load from spinning. The switch opens the

Enable or STOP input which disables the drive. The

control inputs must be removed and reapplied to the

drive for motion to resume after a STOP or Enable

input has been interrupted.

Jumpered Inputs

Carefully review electrical schematics when replacing

a drive. Some machine models jumper the STOP and/

or ENABLE inputs to the drive (refer to Figure 17).

NOTE: Verify that inputs are jumpered. Wire or

metal clip jumpers may be used and can be easily

overlooked during a replacement.

Running Status

Some machines require an output from the drive

indicating the drive is running. TB2-19 and TB2-20

connect to the computer (V-Computer, EDC). The

drive connects the two terminals with a solid state

switch to indicate the drive is running.

CAUTION

MACHINE DAMAGE AND/OR PERSONAL

INJURY. Balance output terminals TB2-9

and TB2-10 should never be jumpered. This

action will force machine beyond

designated tolerances.

CAUTION

MACHINE DAMAGE AND/OR PERSONAL

INJURY. Never jumper inputs if not

previously configured with jumpers as

identified on the applicable electrical

schematic. Jumpering these inputs will

override safety features.
