• Speed command
Use pin number 19 and 20 of CN1 for speed command.
EXT DC 10V
­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] × 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 6.1 A. Speed Command)
