Digital Inputs
S1
Multi-function input 1 (Closed: Forward run, Open:
Stop)
Photocoupler
24 Vdc, 8 mA
Note: Drive preset to sinking mode. When using source mode, set
DIP switch S3 to allow for a 24 Vdc (±10%) external power
supply. Refer to Sinking/Sourcing Mode Switch on page 62.
S2
Multi-function input 2 (Closed: Reverse run, Open:
Stop)
S3 Multi-function input 3 (External fault (N.O.)
S4 Multi-function input 4 (Fault reset)
S5 Multi-function input 5 (Multi-step speed reference 1)
S6 Multi-function input 6 (Multi-step speed reference 2)
SC Multi-function input common (Control common) Sequence common
Safe Disable
Input
HC Power supply for safe disable input +24 Vdc (max 10 mA allowed)
H1 Safe disable input
Open: Output disabled
Closed: Normal operation
Note: Disconnect wire jumper between HC and H1 when using
the safe disable input. The wire length should not exceed 30 m.
Main
Frequency
Reference
Input
RP Multi-function pulse train input (frequency reference)
Response frequency: 0.5 to 32 kHz
(Duty Cycle: 30 to 70%)
(High level voltage: 3.5 to 13.2 Vdc)
(Low level voltage: 0.0 to 0.8 Vdc)
(input impedance: 3 kΩ)
+V Analog input power supply +10.5 Vdc (max allowable current 20 mA)
A1
Multi-function analog input 1 (frequency reference)/
PTC Input
Input voltage 0 to +10 Vdc (20 kΩ) resolution 1/1000
Use DIP switch S4 on the terminal board to selection between
analog or PTC input.
A2 Multi-function analog input 2 (frequency reference)
Input voltage or input current (Selected by DIP switch S1 and H3-
09) 0 to +10 Vdc (20 kΩ), Resolution: 1/1000
4 to 20 mA (250 Ω) or 0 to 20 mA (250 Ω), Resolution: 1/500
AC Frequency reference common 0 Vdc
Type
<1> Refrain from assigning functions to terminals MA and MB that involve frequent switching, as doing so may shorten relay performance life.
Switching life is estimated at 200,000 times (assumes 1 A, resistive load).
<2> Connect a flywheel diode as shown below when driving a reactive load such as a relay coil. Diode must be rated higher than the circuit voltage.
<3> When set for sourcing: use with load of 1.5 kΩ for an output of +5 V, 3.5 kΩ for an output of +8 V, and 10 kΩ for an output of +10 V.
<4> When set for sinking, the external power supply should be +12 Vdc, ±5% with 16 mA or less.
