    Make sure the 6-pin connector at the top of the bleeder unit is correctly plugged in. There isn't a lot of room and can be difficult to plug in especially if the male pins on the bleeder are bent. You can measure the bleeder resistors easily from the 4-pin X3 connector at the bottom front of the DC-Link (rectifier). It should be a between 10 & 15 ohms if I remember correctly. If the bleeder checks good, try changing the DC-Link.


    The teach pendant issue may be separate, try another pendant to see if it makes a difference with the 20175 error.
