A communication fault may occur due to several reasons: * Using the wrong cable, so use a null-modem cable. * The cable might be plugged into the wrong position on the servo amplifier or PC, so plug the cable into the correct sockets. * The wrong PC interface might be selected, so select the correct interface.
What to do if Kollmorgen Amplifier drive reports following error?
If the drive reports a following error, it could be because I or I rms peak is set too low, so increase I or I rms peak, but keep within motor ratings. Alternatively, the accel/decel ramp might be too long, so shorten the ramp +/-.
What to do if Kollmorgen Amplifier motor does not rotate?
If the motor does not rotate, several factors could be at play. Ensure the servo amplifier is enabled by applying the ENABLE signal and that the software enable is set. Check the setpoint cable for any breaks and verify that the motor phases are correctly sequenced. Confirm that the brake is released and that the drive is not mechanically blocked. Also, ensure the motor pole number and feedback are set up correctly.
Why does my Kollmorgen Amplifier motor oscillate?
Motor oscillation can occur if the gain is too high in the speed controller; reduce Kp (speed controller) to resolve this. Another cause could be a broken feedback cable shielding, in which case you should replace the feedback cable. Also, ensure AGND is wired up by joining it to CNC-GND.
What causes Kollmorgen S7240 Amplifier drive to run roughly?
If the drive runs roughly, it could be due to several reasons. The Kp (speed controller) might be too high, so reduce it. Alternatively, the Tn (speed controller) might be too low, so use the motor default value. Also, ARLPF / ARHPF might be too low, so increase them. Finally, ARLP2 might be too low, so increase it.
What causes Kollmorgen S7240 Amplifier motor overheating?
Motor overheating can occur if the I / I rms peak is set too high, so reduce I / I rms peak.
Why is my Kollmorgen S7240 drive too soft?
A drive might feel too soft due to several reasons. The Kp (speed controller) could be too low, so increase it. The Tn (speed controller) might be too high, so use the motor default value. Also, ARLPF / ARHPF might be too high, so reduce them. Finally, ARLP2 might be too high, so reduce it.
How to stop axis drifts at setpoint = 0V in Kollmorgen S7240 Amplifier?
Axis drift at setpoint = 0V may be due to the offset not being correctly adjusted for analog setpoint provision; adjust the offset (analog I/O). Another cause could be AGND not joined to the controller-GND of the controls; join AGND and controller-GND.
