This parameter is used to set the clocking of the internal timer of the inverter. The internal timer is triggered
by an external signal which is set with parameters b-63~b-69. When the external signal is triggered, the
relative OC terminal will generate a valid pulse (which has a width of 0.5s) after a set time.

This parameter is used to control how the internal counter is working. The timer of the counter is set with
parameters b-68 and b-69.
When the counter reaches the value set with C-12 for an external timer, the corresponding OC terminal will
generate a valid pulse signal which has a width of the external timer period.
When the counter reaches the value set with C-13 for an external timer, the corresponding OC terminal will
generate a valid pulse signal. The counter will continue counting until reading is over the value set with
C-12, then it will be cleared, and the valid pulse signal will be released.
The clocking period of the counter must be more than 5ms, and the pulse width must be at least 2ms. The
internal counter is shown as diagram 5-27.
