6.6.5 Motor Overheat Protection
Function Code Parameter Name
F9-56 Type of motor temperature
sensor
F9-57 Motor overheat protection
threshold
F9-58 Motor overheat pre-warning
threshold
A motor temperature sensor can be connected to AI3 and PGND on extension I/O card. This
input is used by the drive for motor overheat protection.
When input signal reaches the value set in F9-57, the AC drive detects Err25 and acts as
selected in thousands position in F9-48. When input signal reaches the value set in F9-58, digital
output terminal set for function 39 becomes on.
The drive supports both PT100 and PT1000. Make sure to set sensor type correctly. You can
view motor temperature in U0-34.
6.6.6 Power Dip Ride-through
The power dip ride-through function ensures the system to run continuously at occurrence of
momentary power loss.
When an instantaneous power loss occurs, the AC drive compensates DC bus voltage reduction
with real-time energy feedback by reducing output frequency, preventing the AC drive from
stopping due to undervoltage.
●
F9-59 = 1: It is applicable to large-inertia applications such as fan, water pump and centrifuge
●
F9-59 = 2: It is applicable to the textile industry.
