43 @TB10A (TERMINAL TB-10A SCALING)

This parameter scales the analog output signal at TB-10A. This setting is the output frequency that is indi-

cated when the TB-10A output measures 10 VDC.

Example: The drive is connected to a control system that requires a 0-5 VDC signal to indicate 0-60 Hz

output frequency. If this parameter were set to 120 Hz, the drive would output 10 VDC at 120 Hz, and 5

VDC at 60 Hz. If the drive is only operated from 0-60 Hz, the control system would only receive the desired

0-5 VDC signal from the drive.

44 TB10B OUT (TERMINAL TB-01B OUTPUT)

The analog output signal at TB-10B is proportional to the drive load. This parameter selects whether that

signal is 0-10 VDC or 2-10 VDC. The 2-10 VDC signal can be converted to a 4-20 mA signal by con-

necting a resistor in series with the signal such that the total load resistance is 500 ohm.

NOTE: This output cannot be used with "loop-powered" devices that derive power from a 4-20 mA signal.

45 @TB10B (TERMINAL TB-10B SCALING)

This parameter scales the analog output signal at TB-10B. The value programmed into this parameter is the

drive load at which the maximum output signal (10VDC) at TB-10A is desired.

Example: The drive is connected to a control system that requires a 0-10 VDC signal to indicate 0-150%

drive load. If this parameter were set to 150%, the drive would output 10 VDC at 150% load, and about

6.7 VDC at 100% load.

NOTE: The output signal at TB-10B is affected by the setting of Parameter 34 - LOAD MLT.

47 TB13A (TB-13A INPUT FUNCTION)

This parameter is used to select the function of terminal TB-13A. Closing TB- 13A to TB-2 activates the

TB-13A input function. The following functions can be selected.

NONE Disables the TB-13A function.

0-10VDC Selects 0-10 VDC as the AUTO speed reference input. The 0-10 VDC signal is wired

to TB-5A and TB-2.

4-20 MA Selects 4-20 mA as the AUTO speed reference input. The 4-20 mA signal is wired to

TB-5B and TB-2.

SPEED#1 Selects PRESET SPEED #1 as the AUTO speed reference.

LOC SEL Selects LOCAL mode when Parameter 30 - CONTROL is set to BOTH. Drive is in

REMOTE mode if contact closure is not made.

DEC FREQ Decrease frequency setpoint. Used with the MOP (motor operated pot) function. Refer

to Section 14.2.6 - SPEED REFERENCE SELECTION.
