5.6 Dwell Operation
The dwell operation is used to maintain torque during the application and release of the
mechanical 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 are 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.
