Hoist Application Preset Specifics
n
This section lists some important points when using the Hoist Application Preset (A1-06 = 6).
Conditions for Opening and Closing the Holding Brake
Use an output signal as described below to operate the holding brake in a hoist application.
Make sure that frequency detection is set so that it does not operate during baseblock (L4-07 = "0"). Even when an external baseblock command is present,
the output frequency will rise when a run command is entered. If frequency detection were to be enabled during baseblock, (i.e., L4-07 = 1) then the brake
would be improperly released. To activate and release the brake using the multi-function output terminals P2-PC, program the drive as shown in the table
below:
Brake Open/Close
Function Parameter
L4-07 = 0
Frequency Detection 2
H2-03 = 5
<1> This setting range is available when using OLV Control. In V/f Control, set the level as the motor rated slip frequency pulse 0.5 Hz. Not enough motor torque will be created if this value is
set too low, and the load may tend to slip. Make sure this value greater than the minimum output frequency and greater than the value of L4-02 as shown in the diagram below. If this value
is set too high, there may be a jolt at start.
<2> Adjust Hysteresis for Frequency Detection 2 by changing the frequency detection width (L4-02) between 0.0 and 0.5 Hz. If the load slips during stop, make incremental changes of 0.1 Hz
until the load no longer slips.
Sequence Circuit Design for Opening and Closing the Holding Brake
Design the braking sequence as follows:
The brake should release when terminal P2-PC closes in response to the run conditions on the sequence side.
When a fault signal is output, the brake should close. When an up or down command is entered, the brake should release.
