Electronic Thermal Relay Selection (Motor 1, 2); Electronic Thermal Characteristic For Motor 1, 2; Heat Sink Over-Heat (Oh) Warning - Delta C2000 series User Manual

Electronic Thermal Relay Selection (Motor 1)

Electronic Thermal Relay Selection (Motor 2)

Settings
 It is used to prevent self-cooled motor overheats under low speed. User can use electronic thermal
relay to limit driver's output power.
Electronic Thermal Characteristic for Motor 1

Electronic Thermal Characteristic for Motor 2

Settings
 The parameter is set by the 150% of motor rated current and the setting of Pr.06-14 and Pr.06-28 to
prevent the motor damaged from overheating. When it reaches the setting, it will display
"EoL1/EoL2" and the motor will be in free running.

Heat Sink Over-heat (OH) Warning


Settings
 Pr.06-15 sets the heatsink temperature level of the drive. The drive will output an overheating
warning when the temperature exceeds the setting of Pr.06-15. If the setting of Pr.06-15 is higher
than the default setting of the drive, the drive will use the default setting level for warning output.
Capacitor (CAP) overheating level is set by the drive's default setting, it can not be adjusted.
