39 TB5 MIN (TERMINAL TB-5 INPUT)

This parameter selects the output frequency of the drive that will correspond to the minimum

analog speed reference input (0 VDC or 4 mA). This parameter is used in conjunction with

Parameter 40 - TB5 MAX to define a speed range for the drive that corresponds to the

analog speed reference input (0 - 10 VDC or 4 - 20 mA).

40 TB5 MAX (TERMINAL TB-5 INPUT)

This parameter selects the output frequency of the drive that will correspond to the maximum

analog speed reference input (10 VDC or 20 mA). This parameter is used in conjunction

with Parameter 39 - TB5 MIN to define a speed range for the drive that corresponds to the

analog speed reference input (0 - 10 VDC or 4 - 20 mA).

Example: The drive is required to operate from 0 to 60 Hz in response to a 0-5 VDC speed

reference signal (rather than the “normal” 0-10 VDC). Because TB5 MAX is based on a 0-

10 VDC (or 4-20 mA) signal, the drive will operate at half of the TB5 MAX value if it is

given a 5 VDC signal. Therefore, setting TB5 MAX to 120 Hz will cause the drive to run at

60 Hz when it is given a 5 VDC speed reference signal.

NOTE: The drive can be programmed for inverse operation so that as the speed reference

increases, the drive speed will decrease, and as the speed reference decreases, the drive speed

will increase. This is accomplished by setting TB5 MIN to the desired maximum output

frequency, and TB5 MAX to the desired minimum output frequency.

42 TB10A OUT (TERMINAL TB-10A OUTPUT)

The analog output signal at TB-10A is proportional to the output frequency of the drive.

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 connecting a resistor in series with the signal such

that the total circuit resistance is 500 Ohms. If set to NONE, the function is disabled.

NOTE: This output cannot be used with “loop-powered” devices that derive power from a

4-20 mA signal.
