When P1-64.Y = 1, servo drive will regard the motor’s current position as the position
corresponded to analog command. Thus, motor will not operate when servo on. See figure 4.3.4,
the input voltage is +5V, motor operates 50 cycles then servo off. Adjust the input voltage to +7V,
then, the 50
th
cycle where motor currently stops will be regarded as the position corresponded to
+7V when servo on. That is why motor does not run.

Servo off the drive when it is
5 V. Adjust the command to
7 V and servo on again.
When servo on, the servo drive would regard
the motor current position as the position
corresponded by current voltage command.
Figure 4.3.4 Voltage command corresponds to the current position when Servo ON
Step 5: Setup the operation method of analog input command
DI: 0x0C sets the latch function of analog position command. When this DI is on, motor will be
held at current position. During the time when DI is on, motor will not operate even when the
analog command is changed. When this DI is off, the motor will complete the command during
the time the DI is triggered. See figure 4.3.5, the input voltage is +5V, motor operates 50 cycles.
Then DI is on. During the time of DI on, adjust the input voltage to +7V. When DI is off, motor will
operate 20 cycles to the position of 70
th
cycle.
