Data 0A : Accel/Decel Speed Prohibit (HOLD Command)
As long as the HOLD command is present, accel and decel are in a prohibit state, and the
output frequency is held at the level it was at the time the HOLD command was input.
When the HOLD command is removed while the system is still in Run condition, accel or
decel will again become active to allow output to reach set frequency. If Stop is initiated
while the HOLD command is present, the prohibit state is cancelled and the system enters
stop operation.
