5.6 Dwell Operation
The dwell operation is used to manitain torque during the application and release of the brakes on
lift-type loads. Inverter dwell operation is based on the Acc/Dec dwell frequency and the dwell
time set by the user. The following points also affect dwell operation:
• Acceleration Dwell Operation: When an operation command runs, acceleration continues
until the acceleration dwell frequency and constant speed is reached within the acceleration
dwell operation time (Acc Dwell Time). After the Acc Dwell Time has passed, acceleration is
carried out based on the acceleration time and the operation speed that was originally set.
• Deceleration Dwell Operation: When a stop command is run, deceleration continues until
the deceleration dwell frequency and constant speed is reached within the deceleration dwell
operation time (Dec Dwell Freq). After the set time has passed, deceleration is carried out
based on the deceleration time that was originally set, then the operation stops.
When dr.09 (Control Mode) is set to 0 (V/F), the inverter can be used for operations with dwell
frequency before opening the mechanical brake of lift-type loads, such as an elevator.
