F10 – Start/Stop Control
Factory Setting: “000” [Keypad Operation] –
F10 is used to set either keypad
operation or external start/stop control. F10 is factory set to “000”, which pro-
vides start/stop control with the keypad. (Also see F03).
Note:
If F10 is set to “001” [External Run/Stop Contacts], the Stop Function on
the keypad (RUN/STOP key) remains operational.
F11 – Frequency Control Method
Factory Setting: “000” [Keypad Operation] –
F11 is used to set the drive for
either keypad control or external signal input control (speed potentiometer, 0 - 10
V, 0 - 20 mA DC, or 4 - 20 mA DC). F11 is factory set to “000”, to operate the
drive using the keypad.
Note:
If a remote speed potentiometer or a 0 - 10 Volt DC signal is used, set SW1
to the “V” position (factory setting). If a 0 - 20 mA DC or 4 - 20 mA DC signal is
used, set SW1 to the “I” position. See Section V-B, starting on page 20.
F12 – Switching Frequency
Factory Setting: “005” [8 kHz] –
F12 is used to set the switching frequency. F12
is factory set to “005”, for a switching frequency of 8 kHz, which provides low
motor noise and good motor torque. Increasing the switching frequency to the
maximum of 16 kHz will further reduce motor noise. However, increased radio fre-
quency interference will result as well as 10% derating of the maximum output cur-
rent. Reducing the switching frequency will provide increased motor torque.
However, the audible noise will also increase.
