Procedure Of External Resistance Calibration - YASKAWA YWE-EH500-6N0 Instruction Manual

HW0480311

14.2 Procedure of External Resistance Calibration

The following outlines how to calibrate the external resistance. For details, refer to the
following sections.
1. Connect the cable for resistance measurement. (Refer to " 14.2.1 Connecting the
Cable for Resistance Measurement ".)
2. Measure the external resistance value and confirm the display. (Refer to " 14.2.2 Mea-
suring the External Resistance Value " and " 14.2.3 Display of External Resistance
Setting Parameter ".)
3. Set the D parameter for calibration of the external resistance to "enabled." (Refer to "
14.2.4 Setting the D Parameter for Calibration of External Resistance to "Enabled" ".)
14.2.1
Connecting the Cable for Resistance Measurement
• Use a machine tool, etc. to securely tighten the connecting section of
the cable for resistance measurement. Since approx. 300 A current
flows at measurement of the external resistance, excessive heat gener-
ation may damage the devices in case of insufficient tightening.
• After moving the manipulator for connection of the cable for resistance
measurement, be sure to turn OFF the power supply of the robot control-
ler.
Unexpected motion of the manipulator during measurement may result in equipment
damage or personal injury.
