1) Speed control
2) Torque control
*1 For the fan of the 7.5kW or less dedicated motor, the
power supply is single phase (200V/50Hz, 200 to 230V/
60Hz).
*2 Assign OH (external thermal input) signal to the terminal CS.
([ Pr. 186 = 7])
Connect a 2W1k
Ω
resistor between terminals PC and CS (OH).
Install the resistor pushing it against the bottom part of the
terminal block so as to avoid a contact with other cables.
Refer to page 37 for details of [ Pr. 186 CS terminal function
selection ].
*3 The pin number differs according to the encoder used.
Speed control and torque control are properly performed
even without connecting Z-phase.
*4 The encoder should be coupled on the same axis with
the motor shaft without any mechanical looseness.
Speed ratio should be 1:1.
*5 Earth (Ground) the shielded cable of the encoder cable
to the enclosure with a P clip, etc. (Refer to page 91)
*6 For the complementary, set the terminating resistor
selection switch to OFF position. (Refer to page 86)
*7 A separate power supply of 5V/12V/15V/24V is
necessary according to the encoder power specification.
When performing encoder feedback control and vector
control together, an encoder and power supply can be
shared.
*8 Refer to page 88 for terminal compatibility of the FR-
JCBL, FR-V7CBL and FR-A7AP.
