SAMI G S 1 Run Enable DI1 This parameter selects the source of the Run Enable signal. 0 V DC = Stop and +24 V DC = Start (Rotation direction is fixed to Forward). YES DI1,2 Run Enable signal active. DI1...DI6 Start/Stop is connected to DI1 and Reverse to D2. DI2 = 0 V DC = Forward and DI2 = +24 V DC = Reverse. To activate the Run Enable signal, the selected Digital Input must be connected to +24 V DC. If the Digital Input comes to 0 V DC, the drive will coast to stop. DI1P,2P Start/Stop commands are given separately using pulse signals. Start is connected to DI 1 and is activated with +24 V DC pulse if Stop (DI2) is connected to +24 V DC.
During normal operation, DI2 is connected to +24 V DC. If DI2 is disconnected with a pulse, SAMI GS stops. STD COMMU Run Enable signal can be activated via RS 485 serial link. 2 Ext Cont Place Sel DI1P,2P,3 This parameter defines how to select the external control place (EXT REF1/EXT REF2). DI1 and DI2 as previously. Reverse is connected to DI3. 0 V DC = Forward, +24 V DC = Reverse. KEYPAD DI1P,2P,3P The selection is made with Operating Data parameter 12 EXT REF 1 OR 2. Start and Reverse commands are given simultaneously with two separate pulses. Stop command is given separately. Start Forward is connected to DI1 and is activated with +24 V DC pulse if Stop (DI3) is con- nected to +24 V DC.
Start Reverse is con- nected to DI2 and is activated as Start Forward. Stop is connected to DI3. During normal operation, DI3 is connected to +24 V DC. IF DI3 is disconnected with a pulse, SAMI GS stops. DI1...DI6 Choose a Digital Input; 0 V DC = EXT REF1 and +24 V DC = EXT REF2. STD COMMU Selection of external reference via serial link RS 485. 3 Ext 1 I/O Cont Sel 4 Ext 2 I/O Cont Sel DI6 This parameter selects the Digital Inputs used for Start/Stop and Reverse commands when using External Reference 1 (External Ref. 2). DI6 = 0 V DC = Stop and DI6 = +24 V DC = Start. Rotation direction is fixed to Forward.
DI6,5 NOT SEL Start/Stop is connected to DI6 (as previ- ously) and Reverse to the DI5. DI5 = 0 V DC = Forward. No Digital Input selected. 38
