Table 3.22 Drive Multi-function Input Terminals
Type Terminal Name (Default) Function (Signal Level)
MFDI
S1
MFDI selection 1
(Not used)
Multi-Function Digital Input
• Photocoupler
• 24 V, 6 mA
Note:
Install the wire jumpers between terminals SC-SP and SC-SN to set the MFDI power supply
(sinking/sourcing mode or internal/external power supply).
• Sinking Mode: Install a jumper between terminals SC and 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: Install a jumper between terminals SC and 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: No jumper necessary between terminals SC-SN and terminals SC-SP.
S2
MFDI selection 2
(Not Used)
S3
MFDI selection 3
(External Fault (NO-Always-Coast))
S4
MFDI selection 4
(Not used)
S5
MFDI selection 5
(Multi-Step Speed Reference 1)
S6
MFDI selection 6
(Multi-Step Speed Reference 2)
S7
MFDI selection 7
(Jog Reference Selection)
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
Safe Disable Input
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 2 ms.
Note:
Safe disable inputs are only effective in Drive Mode. They will not function in Bypass Mode.
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.
Analog
Inputs
+V Power supply for frequency setting
Power Supply for Multi-Function Analog Input
• 10.5 V (allowable current 20 mA maximum)
A1 MFAI1
Voltage input or current input
Select terminal A1 with Jumper switch S1 and H3-01 [Terminal A1 Signal Level Select].
• 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)
A2 MFAI2
Voltage input or current input
Select terminal A2 with Jumper switch S1 and H3-09 [Terminal A2 Signal Level Select]
• 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 Analog input common
Signal Ground for Multi-Function Analog Input
• 0 V
FE Connecting shielded cable Frame Earth
