Chapter 6 Protective Trip and Warning Functions
Trip function and stop the motor before damage and loss of production can
occur.
Stall Trip
The E300 relay trips with a Stall Trip indication when:
• No trip currently exists
• Stall protection is enabled
• Current is present
• The maximum phase current is greater than the Stall Trip Level for a time
p
erio
d greater than the Stall Enabled Time
If the E300 relay trips on a stall, the:
• TRIP/WARN LED status indicator flashes a red 4-short blink pattern
• Bit 3 in Current Trip Status Parameter 4) sets to 1
• Bit 0 in Device Status 0 (Parameter 20) sets to 1
• Any relay outputs configured as a Trip Relay open
• Any relay outputs configured as a Control Relay open
• Any relay outputs configured as a Trip Alarm close
• Any relay outputs configured as a Normal Relay are placed in their
P

ction Fault state (if so programmed)
IMPORTANT
The Protection Fault State of Relay 0, Relay 1, Relay 2, Digital Module 1 Output
Relays, Digital Module 2 Output Relays, Digital Module 3 Output Relays, and
Digital Module 4 Output Relays are defined by the respective parameters:
• Output PT00 Protection Fault Action (Parameter 304)
• Output PT00 Protection Fault Value (Parameter 305)
• Output PT01 Protection Fault Action (Parameter 310)
• Output PT01 Protection Fault Value (Parameter 311)
• Output PT02 Protection Fault Action (Parameter 316)
• Output PT02 Protection Fault Value (Parameter 317)
• Output Digital Module 1 Protection Fault Action (Parameter 322)
• Output Digital Module 1 Protection Fault Value (Parameter 323)
• Output Digital Module 2 Protection Fault Action (Parameter 328)
• Output Digital Module 2 Protection Fault Value (Parameter 329)
• Output Digital Module 3 Protection Fault Action (Parameter 334)
• Output Digital Module 3 Protection Fault Value (Parameter 335)
• Output Digital Module 4 Protection Fault Action (Parameter 340)
• Output Digital Module 4 Protection Fault Value (Parameter 342)
