Type Terminal Name (Default) Function (Signal Level)
MFDI
S1
MFDI selection 1
(ON: Forward run, OFF: Stop)
• Photocoupler
• 24 V, 6 mA
Note:
To set the MFDI power supply (Sinking/Sourcing Mode or
internal/external power supply), install or remove a jumper
between terminals SC-SP or SC-SN depending on the application.
• Sinking Mode, Internal power supply: Install the jumper to close
the circuit between terminals SC-SP.
NOTICE: Damage to Equipment. Do not
close the circuit between terminals SC-SN. If
you close the circuits between terminals SC-
SP and terminals SC-SN at the same time, it
will cause damage to the drive.
• Sourcing Mode, Internal power supply: Install the jumper to
close the circuit between terminals SC-SN.
NOTICE: Damage to Equipment. Do not
close the circuit between terminals SC-SP. If
you close the circuits between terminals SC-
SP and terminals SC-SN at the same time, it
will cause damage to the drive.
• External power supply: Remove the jumper from the MFDI
terminals. It is not necessary to close the circuit between
terminals SC-SP and terminals SC-SN.
S2
MFDI selection 2
(ON: Reverse run OFF: Stop)
S3
MFDI selection 3
(External fault (N.O.))
S4
MFDI selection 4
(Fault reset)
S5
MFDI selection 5
(Multi-step speed reference 1)
S6
MFDI selection 6
(Multi-step speed reference 2)
S7
MFDI selection 7
(Jog command)
SN MFDI power supply 0 V
MFDI power supply, 24 V (maximum 150 mA)
NOTICE: Damage to Equipment. Do not close
the circuit between terminals SP-SN. If you close
the circuits between terminals SC-SP and
terminals SC-SN at the same time, it will cause
damage to the drive.
SC MFDI selection common
SP MFDI power supply +24 Vdc
Safe Disable Input
H1 Safe Disable input 1
Remove the jumper between terminals H1-HC and H2-HC to use the
Safe Disable input.
• 24 V, 6 mA
• ON: Normal operation
• OFF: Coasting motor
• Internal impedance 4.7 kΩ
• OFF Minimum OFF time of 3 ms.
H2 Safe Disable input 2
HC Safe Disable function common
Safe Disable function common
NOTICE: Do not close the circuit between
terminals HC and SN. A closed circuit between
these terminals will cause damage to the drive.
Master Frequency
Reference
RP
Master frequency reference pulse train input
(Master frequency reference)
• Response frequency: 0 to 32 kHz
• H level duty: 30% to 70%
• H level voltage: 3.5 V to 13.2 V
• L level voltage: 0.0 V to 0.8 V
• Input impedance: 3 kΩ
+V Power supply for frequency setting 10.5 V (allowable current 20 mA maximum)
A1
MFAI1
(Master frequency reference)
Voltage input
• 0 V to 10 V/100% (input impedance: 20 kΩ)
A2
MFAI2
(Combined to terminal A1)
Voltage input or current input
Use DIP switch S1 and H3-09 [Terminal A2 Signal Level Select] to
select the input.
• 0 V to 10 V/100% (input impedance: 20 kΩ)
• 4 mA to 20 mA/100%, 0 mA to 20 mA/100% (input impedance:
250 Ω)
AC Frequency reference common 0 V
