Operation Function

Operation function
The inverter has the following control functions that are made active from the operation
panel and terminal block.
Operation control
Jogging
Free-run stop
DC brake
Positioning DC
brake
DC brake for
full-range stop
Acceleration/deceleration time is set to "0". This function is optimum for
positioning. By setting [
jogging operation is enabled.
When the "I3" and "G" control input terminals are short-circuited, CCW
jogging is enabled. When "I4" and "G" are short-circuited, CW jogging is
enabled, and the jogging frequency is output.
You can switch over between the normal operation mode and the jogging
mode.
The jogging frequency can be specified in the range of 0 to 30 Hz. If the
jogging frequency is too high, the inverter may trip due to overcurrent.
Turns off the output voltage applied to the motor, allowing the motor to coast.
This function is useful to brake the motor mechanically.
touching the motor output terminals (U/T1, V/T2 and W/T3) may cause
electric shock even if the free-run stop function is activated.
Activates the brake by applying a direct current to the motor at the time
when the inverter shifts from the running status to the stop status. If the
CCW, CW or jogging command is issued while the DC brake function is
activated, the DC brake is disabled, and the motor starts running as
specified by the command.
When a stop command is issued during normal operation, the motor
soft-stops, and the DC brake is activated when the output frequency is
reduced to 3 Hz. (The frequency at which the brake is activated can be
changed with the parameter).
When the frequency is set to "0", the DC brake is activated when the output
frequency falls below 1 Hz.
The DC brake intensity (torque) and time can be specified with the
parameters.
When a stop command is issued during normal operation, the DC brake is
immediately activated without soft-stop.
The DC brake intensity (torque) and time can be specified with the
parameters.
The DC brake time is twice as long as the time specified for "Positioning DC
brake".
