Common terminal of terminal 6 and the DA1.
Enter thermistor output signal for the motor dedi-
cated to vector control (SF-V5RU)
When calibrating at installation, change the
switch to place the inverter in calibration status.
*1 Use terminals SD or PC on the inverter.
*2 AY41 type unit requires 24VDC power.
Example of connection with the output module (AY41
type) of Mitsubishi programmable controller. Refer to the
output module manual for details of the output module.
*3 The control logic is the same as that of the inverter
(factory-set to sink). When the logic of the inverter is
changed to source, the option logic also switches to
source. To change the control logic, refer to page 40.
*4 As the input signals are at low level, use two parallel
micro signal contacts or a twin contact for relay contact
inputs to prevent a contact fault.
Micro signal contacts
*5 A transistor of the following specifications should be
selected for the open collector signal:
Electrical characteristics of the transistor used
• Ic ≥ 10mA
• Leakage current: 100µA or less
• VCE ≥ 30V
• When Ic ≥ 10mA, VCE(sat) voltage 3V or less.
