Remote Input

The Remote input is an optically isolated input that uses an ILQ2

quad OPTO isolator. The REMOTE+ terminal is connected to the

anode of the OPTO lead via a 681Ω current limiting resistor. The

REMOTE- terminal is connected to the cathode of the OPTO lead.

The OPTO requires a minimum of 3.5 mA (≈3.5VDC) to ensure proper

system operation.

This input allows you to reduce current to a motor from a remote

location. This is accomplished by changing the current select

resistor via the remote input. When the remote input is enabled, the

open collector transistor connected to the REMOTE screw terminal

will conduct to ground. If the CURRENT and REMOTE terminals are

shorted together (with a wire) motor current will be reduced to zero.

Motor current can also be reduced by a percentage if CURRENT and

REMOTE are shorted with the appropriate resistor. A remote motor

current value must be selected (see Table 2-8) to set the operating

current. Identify the current resistor associated with the operating

current you select. Use the resistor values to determine the remote

resistor that must be installed between the CURRENT and REMOTE

terminals. Use the following equation to detemine R

REMOTE

= -13,300 (3650 + R

) / (R

)

Fault Output

This output is an open-collector, open emitter output from a ILQ2

OPTO isolator. The output transistor will conduct when the drive is

functioning properly. The transistor will not conduct properly when

any of the following conditions exist.

❏ No power is applied to the drive

❏ There is insufficient voltage (<24VDC)

❏ The driver detects a motor fault

❏ The remote input is enabled

This output has the following electrical characteristics:

❏ V

= 35VDC

❏ V

CESAT

= 0.3VDC

❏ Collector Current = 10 mA maximum

❏ Dissipation = 100 mW maximum
