6A-TOLC
works in conjunction with
67-TOL
to customize the overload characteristics of the
inverter to the driven motor. Refer to the graphic presented with parameter 67 for a more
in-depth understanding of this parameter.
Data codes “0” through “3” provide for the use of a “standard” motor that typically has a lim-
ited continuous constant torque operating speed range. With these data codes, the degree
of overload permitted by the drive depends on the output frequency. Lesser degrees of
overload are permitted at lower speeds.
Data codes “4” through “7” provide for the use of an “inverter duty” motor that has a more
extensive continuous constant torque operating speed range. With these data codes, the
overload performance follows the curve designated “>40 Hz” regardless of operating fre-
quency.
As you adjust between “0” & “3” and “4” & “7”, you get various inverse time characteristics.
Data codes “0” and “4” give you the characteristic depicted by the scale designated “C”.
Data codes “1” and “5” work on scale “B” and codes “2” and “6” on scale “A”. With data
codes “3” and “7”, the parameter
67-TOL
works as an adjustable electronic “shear pin” with
no inverse time characteristic.
*
Trip time is at 150% of
67-TOL
setting.
** Trip time is at 110% of
67-TOL
setting.
◊
Value range: 0–7
Default: 0
This parameter adjusts the meter output value at terminal MET1. The setting range is 0–
255.
70-MCAL
can be programmed while the inverter is running.
Factory default is for 10 VDC at terminal MET1, at nominal full scale output.
◊
Value range: 0–255
Default: 210
This parameter selects the analog output signal to be indicated at terminal MET1. The fac-
tory full scale setting is 10 VDC but can be changed using parameter
70-MCAL
.
