Terminals Function Type Electrical characteristics
B5 Serial link, TX Transmission Logic output
Non isolated outputs
0 to 5VDC,
±
60mA
B6 Serial link, TX Transmission Logic output
High logic level (TX = +5V TX = 0V)
Low logic level (TX = 0V TX = 5V)
B7 0V common to terminals A5, A7, C1 and C6 - 0V floating
B8
B9 Selection of preset speeds
Logic input
Selection via a binary combination, (b20 = 0) of
3 preset speeds plus the reference.
B10
Inching (JOG) or extension for preset speeds
Logic input
If b20 = 0 --> Inching (JOG),
If b20 = 1 --> Selection via a binary combination
with B8 and B9 of 7 preset
speeds plus the reference.
C1 0V common to terminals A5, A7, B7 and C6 - 0V floating
C2 Voltage frequency reference Analogue input
Input impedance = 94 k

C5 * Current frequency reference Analogue input
Input impedance = 100
Ω
Current signal = 4 to 20mA, 20 to 4mA, 0 to 20mA
Enable with terminal C11, select with b11
C6 0V common to terminals A5, A7, B7 and C1 - 0V floating
C7 External trip Logic input 0V interrupt = external trip
C8 Reset Logic input 0V pulse = reset
C9 Ramp hold Logic input Connection to 0V = ramp fixed
C10 Forward operation/stop Logic input
Connection to 0V = Forward Operation
Not connected = Stop
Terminals C10 and C12 to 0V = Stop
C11
Selection of frequency reference
Local/Remote
Logic input
Connection to 0V = Remote frequency reference
Not connected = Local frequency reference
C12 Forward operation/stop Logic input
Connection to 0V = Reverse Operation
Not connected = Stop
Terminals C10 and C12 to 0V = Stop
Caution : in positive logic (b5 = 0) the logic inputs are enabled by the +24V.
* For the simultaneous reference of 2 inverters, the 0V must not be commons.
