10.7 ANALOG OUTPUT SIGNALS

Terminal TB-30 can provide a 0-10 VDC or a 2-10 VDC signal proportional to output

frequency, load, or torque. The 2-10 VDC signal can be converted to a 4-20 mA signal using

a resistor in series with the signal such that the total load resistance is 500 Ohms. Refer to

TB-30 OUTPUT (Parameter 08) in Section 15 - DESCRIPTION OF PARAMETERS.

10.8 DRIVE STATUS DIGITAL OUTPUTS

There are two open-collector outputs at terminals TB-14 and TB-15. The open-collector

circuits are current-sinking types rated at 30 VDC and 50 mA maximum.

The open-collector outputs can be programmed to indicate any of the following: RUN,

FAULT, INVERSE FAULT, FAULT LOCKOUT, AT SPEED, ABOVE PRESET SPEED #3,

CURRENT LIMIT, AUTO SPEED MODE, and REVERSE. Refer to Parameters 06 and 13 in

Section 15 - DESCRIPTION OF PARAMETERS.

The following diagram illustrates how the 12 VDC power supply at TB-11 can be used with

the open- collector output to drive an external relay.
