3.2 Setting User Constants According to Host Controller
101
• Always set bit 2 of memory switch Cn-02 to 0.
If bit 2 is set to 1, the contact input speed control function is selected, and the INHIBIT
function cannot be used. (The P-CON signal is used for changing the motor rotation
direction. For the contact input speed function, refer to 3.2.6 Using Contact Input
Speed Control.)

3.2.11 Using the Reference Pulse Input Filter Selection Function
For position control only.
1) Outline
This function selects a reference pulse input filter inside the Servopack according to the
output form of reference pulses from the host controller.
2) How to Use Reference Pulse Input Filter
Set the following memory switch according to the output form of reference pulses from
the host controller:
Cn-02 Bit F

Setting: 0
For Position Control Only
Sets the memory switch according to the output form (line driver or open collector) of ref-
erence pulses from the host controller.
Setting
Meaning
0
Output form of reference pulses from host controller: Line driver output (maximum
frequency of reference pulse: 450 kpps)
1
Output form of reference pulses from host controller: Open collector output
(maximum frequency of reference pulse: 200 kpps)
• For open collector output, the wire length must be as short as possible (maximum 3 m).
