The time since the last start is too short. No immediate start is allowed if the
motor stops when this operand is asserted.
The motor stopped because the time since the last start was too short. No
restart is allowed as long as this operand is asserted (use to inhibit the motor
start command).
The time since the last start is long enough to accommodate the next start
should the motor stop

Same set of operands as shown for TRIP BUS 1
Asserted when the undercurrent element alarm stage picks up
Asserted when the undercurrent element trip stage picks up
Asserted when the undercurrent element alarm stage operates
Asserted when the undercurrent element trip stage operates
Asserted when the speed 2 undercurrent alarm picks up
