(3)AdjustmentVR1: Adjusts the gain of channel 1.
Execute a robot program and set AOUT[1] to 4095 on the teach pendant.Connect a digital voltmeter to test pin AOUT1 and rotate VR1 until the meterreads 12.0 V.Connect the negative (-) lead of the digital voltmeter to test pin GNDF.
VR2: Adjusts the gain of channel 2.Execute a robot program and set AOUT[2] to 4095 on the teach pendant.Connect the digital voltmeter to test pin AOUT2 and rotate VR2 until the meterreads 12.0 V.Connect the negative (-) lead of the digital voltmeter to test pin GNDF. (The
0VF test pin is different from the common 0V test pin.)VR3: Adjusts the reference supply voltage of the digital/analog converter.
Connect the digital voltmeter to test pin P10V and rotate VR3 until the meterreads 10.00.1 V.
VR4, VR5: Internal power supply adjustmentThese VRs are used to adjust the internal supply voltage for the printed circuitboard. They are set at the factory and need not be adjusted.
