Fig 6.30 Input Voltage and Command Torque
Fig 6.31 Torque Command Input Circuit
- During the torque control, input terminal of unused com-
mand must be opened.
- Torque may also change when the analog input voltage
changes thus a precision power supply must be used.
- For accurate torque control, use multi turn precision vari-
able resistor (10-Turn) and when accurate work is not
required relatively, use general variable resistor (1-Turn).
- Command voltage from the host controller or external
circuit has an offset in the vicinity of 0V. In such cases,
operate "Torque Command Auto Offset Adjustment"
(Torque Command Manual Offset Adjustment) from USr-
04 (Usr-06).
