• Speed command
Use pin number 19 and 20 of CN1 for speed command.

Fig 3.7 Speed Command Analog Input

- Speed may change when the voltage changes, thus accurate
external power must be used.
- Open the input terminal, which is not used during the speed control.
- Relationship between input voltage and speed command value
- Speed command value[RPM]=Setting value of SEt-01[RPM/V] x
Input Voltage[V]
Initial value of SEt-01=500.
Thus, when inputting 6V, revolution takes place in 3000[RPM].
- Input voltage is ± 10V Maximum.
- When inputting the 0V using just the variable resistor, the input
voltage cannot reach 0V, thus use the switch as shown above for 0V
input. (In order to stop the motor completely when it has 0V,
operate in Zero-Clamp speed control mode.)
* When the speed command, which the user wants, is not a
multiple of 10, set LED No.2=1 from SEt-46, to change the unit of
SEt-01 as [RPM/10V]. Then, the motor rotates in 1552[RPM] for
10V speed command, if SEt-01=1553 is input. (Refer to Speed
Control )
