3.4.3 Position command pulse input signal
To use the servo driver in position servo mode, input the position command pulse by using the
open collector input, line drive input, and pulse output of the MPG (Manual Pulse Generator) or
PLC position control card using external power supply of 5 [V] and 24 [V]. The types of pulses that
can be used are "dir pulse", "forward pulse + reverse pulse", and "LEAD pulse + LAG
pulse". Select the type of pulse from the [Pulse Logic (P4-14)] menu of the front operation panel
[Position Mode (P4--)] menu.
Photo coupler has been used in the pulse input circuit to insulate the internal control unit of the
drive system from the external pulse signal. However, if 5 [V] is used as the open collector input,
connect 1/2W 150
Ω
resistance, or 1/2W 1.5k
Ω
resistance if 24 [V] is used.

3.4.4 Input contact signal
The function of the input contact signal used to control the drive
system partially changes in the speed control mode, position
control mode, and torque control mode.
Function of each input contact signal is shown on the following
table. The input contacts are classified into A contact and B
contact depending on the contact characteristics. Check before use. Connect external power
supply greater than DC +24 [V], 1 [A] to the +24 [V] power input terminal (CN1-49) to use the
contact input.
Turning on the servo motor drive command signal (CN1-18) will reset the base block of IGBT and
generation braking, turning the servo motor at a speed set by the speed command select signal.
