Command not working

Close Loop command not working was created by nightline
I've a SDC2160 with an electic cylinder connected. This cylinder has a brushed motor and a hall type encoder. I can jog the cylinder back and forward in open loop, and see de counter 1 going up and down, and feedback 1 is showing the speed while moving.
This way I send the cylinder complete out, stop the motion command, home the counter with: setcommand(_Home, 1). Then is switch to closed loop with: setcommand(_MMOD, 1, 3) for example. If I now read the operation mode of motor 1, it always shows a "0", doesn't matter which operating mode I set.
And when I give a positioning command there is no motion. I tried the following commands: setcommand(_PR, cc, nn) , setcommand(_MPOSREL, cc, nn) and setcommand(_MOTPOS, cc, nn).
None of these commands gives a reaction of the controller.
I've set all P gains to 10.
What can be wrong?
Thanks in advance!

Well I found what was wrong, I gave a setcommand for MMOD while this should be a setconfig.
So this is solved, but now I'm facing another issue:
See the code below:
So this is solved, but now I'm facing another issue:
See the code below:
print("starting ... \r")
iSeq = 0
wait(1000)
print("iSeq= ", iSeq," \n")
wait(1000)
if iSeq = 0 then
iseq = iSeq +1
print("iSeq= ", iSeq," \n")
end if
Top:
Speed = abs(getvalue(_S, 1)) ' Read motor speed from Encoders
if iSeq = 1 then
if Speed < 5 then
print("Speed=", Speed," \n")
setconfig(_MMOD, 1, 0) ' Configure channel 1 in open loop mode
wait(10)
OperetingMode = getvalue(_MMOD, 1)
setcommand(_GO, 1, 500) ' Apply 10% reverse command to motor 1
wait(10)
MotorCommand = getvalue(_M, 1)
wait(500)
print("OperetingMode=", OperetingMode," \n")
print("MotorCommand=", MotorCommand," \n")
goto Top
else
iseq = iSeq +1
print("iSeq= ", iSeq," \n")
end if
end if
if iSeq = 2 and Speed = 0 THEN
iseq = iSeq +1
print("iSeq= ", iSeq," \n")
end if
I would expect that my motor starts spinning in the forward direction. With the print commands I can see that the operating mode is 0 ( open loop ) and the speed command is 500, like it should be. But the motor isn't spinning at all....
