F_11: Speed Control
= 0: Keypad
= 1: Analog Speed Pot Terminal (TM2) (0 ~ 10V / 0-20mA)
= 2: Analog Speed Pot Terminal (TM2) ( 4-20mA )
NOTE 1:
When jog frequency or Sp1 frequency is
switched on, the frequency is setup by Sp1
speed, the
▲▼
buttons on the keypad is
disabled.
Original setting will be restored after the Sp1
connection is removed.
NOTE2:
During the contact closure of the jog function,
the keypad control remains in a sleep state until
the jog contact connection is re-opened.

2: If F_12=7~10,the inverter must operator with low load.
Although an IGBT TYPE inverter can provide a low audible noise level during its operation, it is possible
that the switching of the high carrier frequency may interfere with external electronic components (or
other controllers) or even cause vibration in the motor. Adjusting the carrier frequency can usually
correct this problem.
