sent will remain 'depressed' until the timer expires. The default
timer interval is one second. The user can alter this via the Pol
Motor Jog Duration CONFIG mode item. If the last two digits
of the 'Jog Duration parameter are between 2 and 25 the jog
interval will be the value specified by the last two digits
multiplied by 100 milliseconds. For example, a 'Jog Duration
value of 1015 will result in a timer interval of 1500 milliseconds
or 1.5 seconds.
The resolution of the timer is approximately +/- 150
milliseconds.
