  • Page 32 Startup ® Simple startup of MOVITRAC Operation with ±10 V interface with fast analog input on the LTX servo module (sampling cycle = 4 ms) You should use the servo module inputs predominantly if you require reference cams or a fast analog input or a stepper motor control. This will also enable the pulse/direction control or the encoder input function.
  • Page 33 Startup ® Simple startup of MOVITRAC Operation with pulse/direction or A, /A, B, /B (stepper motor control interface) on the server module • CAUTION potential unexpected movement of the motor. Risk of crushing – Perform a reference travel prior to enabling the drive with stepper motor control (P4-01 = 5, PM-Motor, position control).
  • Page 34 Startup ® Simple startup of MOVITRAC • CAUTION unexpected drive response possible. Risk of crushing If functions (e.g. the analog input) are set in parameter P1-15 and activated in parameter P1-17, the input on the X14 connector has priority and the signal assign- ments on parameter P1-15 are overwritten or deactivated.
  • Page 35 Startup ® Simple startup of MOVITRAC ® SEW control mode For operation with an SEW controller with CCU or MOVI-PLC (setup via the "Drive startup" wizard): • Set the required drive address in P1-19 (1 – 63). • Set the required baud rate in P1-20 (125, 250, 500, 1000 kBaud). For CCU mode, the baud rate must be set to 500 kBaud.

  • Page 37: Software

    Startup Software • Set P5-06 to the required "Communication failure time monitoring" (0.0 – 1.0 – 5.0 s). This determines the time in seconds after which the inverter performs the response set in P5-05. With "0.0 s", the inverter maintains the actual speed even if the com- munication fails.
