Notes:
The S-shaped curve frequency change curve is approximated with a 3D function based on a setting value. The setting value of the
•
approximation equation cannot be changed.
The S-shaped curve frequency change curve changes to a linear curve in the following situations.
•
When the frequency change time is less than 100 ms
•
When the initial pulse frequency is less than 100 Hz

10. Reversible control enable
This setting enables or disables reversible control and selects the reversible control method from the following reversible control
modes. There are two modes for the pulse output mode: single-pulse and dual-pulse. They can be combined with reversible
control as follows. (This is an example when RAMP1 is used with the All-in-One CPU module.)
Reversible Control Enable
Reversible control disabled
Reversible control
Single-pulse output
Reversible control
Dual-pulse output
The outputs used on the FC6A Series MICROSmart vary based on the instruction used, the combination of the pulse output
mode and reversible control, and the model used.
Instruction
Reversible control disabled
RAMP1 Reversible control (single-pulse output)
Reversible control (dual-pulse output)
Reversible control disabled
RAMP2 Reversible control (single-pulse output)
Reversible control (dual-pulse output)
Reversible control disabled
RAMP3 Reversible control (single-pulse output)
Reversible control (dual-pulse output)
Reversible control disabled
RAMP4 Reversible control (single-pulse output)
Reversible control (dual-pulse output)
*1 When using single-pulse output mode with the All-in-One CPU module, Q2 or Q3 will be used, so an instruction that uses the same output
cannot be used.
*2 When using dual-pulse output mode with the All-in-One CPU module, Q1 will be used, so an instruction that uses the same output cannot be used.
11. Control direction
When reversible control is enabled, store 0 in this data register for forward operation and store 1 in this data register for reverse operation.
This is ignored when specify absolute position mode is Enabled. If the absolute position counter value subtracted from the target position is
positive, Forward is automatically selected, and pulses are output. If negative, Reverse is automatically selected, and pulses are output.
Total number of pulses
Select this option when using pulse output in a single
direction. Pulse A and pulse B can be used independently.
Pulse A is used as pulse output. Pulse B on/off is used as
reversible control.
Pulse A is used as forward pulse (CW) output.
Pulse B is used as reverse pulse (CCW) output.
