7.2.4 Manual Adjustment of the Speed and Torque Reference Offset
Speed/torque reference offset manual adjustment is very convenient in the following situations:
D
If a loop is formed with the host controller and the error is zeroed when servo lock isstopped.
D
To deliberately set the offset to some value.
This mode can also be used to check the data set in the reference offset automatic adjustment
mode.
In principle, this mode operates in the same way as the reference offset automatic adjustment
mode, except that the amount of offset isdirectly input during the adjustment. The offset amount
can be set in the speed reference or torque reference.
The offset setting range and setting units are as follows:
Reference Speed or Reference Torque
Offset Setting
Range
Offset Units
Analog Input Voltage
Offset Setting Range
Offset Setting Range
Speed Reference: --9999 to +9999
Speed Reference: 0.058 mV/LSB
Torque Reference: --128 to +127
Torque Reference: 14.7 mV/LSB
