method programmed in the control parameter. The bit patterns of the Seq Cntl X” parameters are
shown in Table 4:
Vacon 50X Sequencer Speed Selection
Table 5 gives more information on the speed selection options available in the Vacon 50X sequencer by
programming bits 0, 1, and 2 of each state’s control parameter. The options include any Preset Speed,
MaxFrequency, or allowing the reference to be determined in the normal Vacon 50X control path.
Vacon 50X Sequencer Ramping Selection
When the sequencer is active, the active ramp is no longer determined by parameter “Ramp Select.” The
user, however, does have the choice of using the main ramps (Accel Time 1/Decel Time1), or the alternate
ramps (Accel Time 2/Decel Time 2) for each independent state. This is determined by bit 3 of the control
parameter. If bit 3 is set to 1, then the alternate ramps are used (Accel Time 2/Decel Time 2).
