Overload Protection Level; Output Overload Warning Level - Delta Electronics ASDA-B Series User Manual

P2 - 36 OVL

Overload Protection Level

Default: 100
Applicable Control Mode: P/S/T
Unit: %
Range: 70 ~ 100
Settings:
100: The overload time will not be extended.
70: The overload time will be extended. The extended overload time is equal to the original
overload time multiply by P2-37/70.
This parameter is used to set the overload protection level that is used to determine the overload
fault condition (ALE06). However, when using this parameter, the operating temperature of the
servo motor should be lower, the ventilation should be adequate for heat dissipation or the motor
should be provided with fans to ensure the surface temperature of the motor will not exceed the
specification.
For example, suppose that ECMA-C30807S servo motor is used, the normal current is 200%
and the overload time is 8 seconds, if P2-36 is set to 100% and P2-37 is set 100% also, the
servo fault message, overload (ALE06) will occur when the overload time, 8 x (100%/100%) = 8
seconds has been reached. However, if P2-36 is set to 70% and P2-37 is set to 100%, the servo
fault message, overload (ALE06) will occur when the overload time, 8 x (100%/70%) = 11.43
seconds has been reached.
P2 - 37 OVW

Output Overload Warning Level

Default: 50%
Applicable Control Mode: P/S/T
Unit: N/A
Range: 0 ~ 100%
Settings:
This parameter is used to set the output overload warning level that is used to activate the DO
signal OLW. (See Table 7.B). When the motor has reached the output overload level set by
parameter P2-37, the motor will send a warning to the drive. After the drive has detected the
warning, the DI signal OLW will be activated.
For example, suppose that ECMA-C30807S servo motor is used, when the normal current is
200%, and the overload time is 8 seconds, if P2-36 is set to 100% and P2-37 is set 100% also,
the servo fault message, overload (ALE06) will be detected and show on the LED display when
the overload time, 8 x (100%/100%) = 8 seconds has been reached. However, if P2-36 is set to
100% and P2-37 is set to 50%, the servo fault message, overload (ALE06) will be detected and
show on the LED display when the overload time, 8 x (50%/100%) = 4 seconds has been
reached.
