Parameter Descriptions 7-37
F58
Overload trip time
Range: 0-60 [sec]
Default: 60
Access Tunable
See Also: F56, F57
The inverter output is turned off if the current level set in F57 is exceeded
for the time set in F58 – Overload trip time.
F59 Stall Prevention select
Range: 0 - 7
Default: 0
Access Configurable

Function Description:
Acceleration
Constant run
Deceleration
t32 and t33:
Example:
Motor starts deceleration when current exceeds the value
set in F60.
Motor decelerates when current exceeds the value set in
F6.
Motor deceleration is stopped when inverter DC link
voltage rises above a certain voltage level.
The drive outputs signals through either the digital (MO) or
relay output (3A~C) terminals when set = 7 Motor Stall.
Motor stall status can be monitored in the above codes
even if F59 is not active.
F59 = 3; stall prevention active during acceleration and
constant run. When stall prevention is executed during
acceleration or deceleration, accel/decel times may take
longer than the user-setting time to prevent a stall
condition. When stall prevention is activated during
constant run, t1, t2 executed in accordance with the value
set in P41 – Accel Time and P42 – Decel Time.
