Run Command; Operation When The External Baseblock Command Is Input And Cleared; Speed Reference - YASKAWA CIPR-CR70A Series Technical Manual

3 Startup Procedure and Test Run
• There is an overvoltage or undervoltage fault during stop, and the drive detects faults and stops when the Run
command is entered
• When the drive is in the Programming mode and will not accept a Run command even when entered
■

Run Command

Run
Before operating the crane, make sure that the Forward Run command rotates the motor to raise the load, and that
the Reverse Run command rotates the motor to lower the load. These conditions must be met to start hoisting or
lowering:
• A speed reference signal set with MFDI is input.
• The Safe Disable signal is input from an external source to terminal H1-HC and H2-HC (this is separate from a
baseblock situation).
• The Software baseblock command signal is not input from any of the MFDI terminals (this is separate from a
baseblock situation).
• The conditions must be met to output a Brake release command.
– Output frequency after a soft start ≥ Brake release frequency
– Output current > Brake release current
– Torque reference ≥ Brake release torque (OLV control only)
• When H1-xx = 0 [Brake Release Check], the magnetic contactor closes.
Stop
When the Run command (Forward or Reverse) is cleared, the crane will stop operation.

Operation When the External Baseblock Command is Input and Cleared

To prevent load slipping when clearing the Baseblock command, the drive does not have a Speed Search function.
Operation When the External Baseblock Command is Input
• The drive executes baseblock (drive output stop) for at least 0.1 s.
When using the brake sequence, the Brake release command is switches OFF.
• Set SFS Output Frequency to 0.
Operation When the External Baseblock Command is Cleared
• Acceleration always starts from the zero speed when the Run command is input.
• The baseblock state is maintained when the Run command is not input.

Name
Use the keypad to enter the Forward Run/Reverse Run command. Use this
operation only in a test run.
Use the control circuit terminals S1 and S2 to enter the Forward Run/Reverse
Run command. Usually, use this setting.
Use MEMOBUS/Modbus communications to enter the Forward Run/Reverse
Run command.
Use an input option card to enter the Forward Run/Reverse Run command.
Name
Use the keypad to enter the speed reference.
Use the MFAI terminals A1, A2, and A3 to enter the speed reference.
Use MEMOBUS/Modbus communications to enter the speed reference.
Use an input option card to enter the speed reference.
