Allen-Bradley 1305-Series AC Drives

The Input Status’ display of 1s and 0s represents the drive’s display of parameter #55. These inputs can be viewed in the status display with a Human Interface Module (HIM or parameter unit). Parameter #55 displays the Input Status. When voltage is high (inactive) for an input, the status display will read “0” (Logic 0). When voltage is low (active) for an input, the status display will read “1” (Logic 1).

Table 44 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 44.

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 40. This action occurs at distribution speed connecting TB2-9 and TB2-10 when the drive detects an acceptable balance condition.

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.

W664

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 40).

NOTE: Verify that inputs are jumpered. Wire or metal clip jumpers may be used and can be easily overlooked during a replacement.

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.

W665

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.
