EMC might well be trying to emit a PWM signal, but it might not be
getting through the hardware abstraction layer, the onboard hardware
or the 7i43.

What do you see looking at the pwm pin in Halscope? If EMC is setting
values there but not seeing the motor move, then it will set a follow
error, because there _is_ a following error.

(Off-topic rant, I am often phoned by people in other sections of the
Major Auto Manufacturer I work for asking us to fix the software bug
that is causing an engine fault to be flagged. Nine times out of ten
it is a genuine fault with the engine being correctly diagnosed)
