Value RC2 random drops to 0 when wheels are powered

We are setting up a GBL2660.

We have a problem reading the pulse inputs (pulse with) on the controller.

We setup the sinus/cosinus encoders correctly and in the roborun untility Both wheels are turing forward/backwards without any issues
We are using the sinusoidal switching mode in Closed Loop Speed Mode 
We use 3 pulse inputs on RC 1, RC2 and RC3 in a range between 1000 and 2000 with a center position of 1500
When the motor controller is not in Estop (wheels are powered) the input of RC2 is random set to 0 for couple of milliseconds. When I set the estop in the roborun utility the value is displayed in the correct way. I checked the wiring with the oscilloscope but I cannot see any voltage drop.or short to GND. I suspect the controller can not sample the RC2 input when the motors are active.
RC1 and RC3 will be read correctly.
I have tried to update the firmware to 2.01 and 2.1. but both firmware versions have the same problem
.How can I solve this?
