41 AIN FLTR (ANALOG INPUT FILTER)
This parameter adjusts the filter on the analog input terminals (TB-5A and TB-5B) to reduce the effect of
any electrical noise that may be present on the analog input signals. This filter works in both PID mode
and standard speed control mode . It should be set to the lowest value that yields acceptable performance, as
setting it too high may cause the drive to react too slowly to signal changes .
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 load 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.
43 @ TB10A (TERMINAL TB-10A SCALING)
This parameter scales the analog output signal at TB-10A. This setting is the output frequency that is
indicated when the TB-10A output measures 10VDC .
Example: The drive is part of a control system that requires a 0-5 VDC signal (rather than 0-10 VDC) that
is proportional to 0-60 Hz output frequency. The output signal is linear, so setting this parameter to 120
Hz would yield 10 VDC at 120 Hz, and 5 VDC at 60 Hz.
44 TB10B OUT (TERMINAL TB-10B 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
connecting a resistor in series with the signal such that the total load resistance is 500 Ohms .
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. This setting is the load (in %) that is indicated
when the TB-10B output measures 10 VDC .
Example: The drive is part of 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 .
