Motor overtemperature Alarm

DESCRIPTION

This alarm appears when:

•

Motor temperature exceeds

Maximum motor temperature

value if set

Temperature probe type

KTY83/122

KTY84/130

•

Motor temperature sensor isn’t connected if

Thermostat

is selected as

Temperature probe type

UNIDRIVE BEHAVIOUR

UNIDRIVE stops motor rotation with emergency slope (disabling

power relay and three-phase bridge) and unlocks motor brake.

POSSIBLE TROUBLESHOOTING ISSUE

If motor hasn’t any PTC, set

none

Temperature

probe type

option (See Section 3.4.6. Otherwise, restore motor temperature

conditions, then reset alarms.

Safety Alarm

DESCRIPTION

This alarm is active when the SAFETY Input (P

12) isn’t supplied.

UNIDRIVE BEHAVIOUR

UNIDRIVE stops motor rotation with emergency slope (disabling

power relay and three-phase bridge) and unlocks motor brake.

POSSIBLE TROUBLESHOOTING ISSUE

Check the connection of SAFETY input and

restart your UNIDRIVE.

Stalled rotor Alarm

DESCRIPTION

This alarm appears when the motor is blocked and at the same time

the phase current is high about for approximately for a second. For instance,

the vehicle’s wheels are blocked by an obstacle.

UNIDRIVE BEHAVIOUR

Drive won’t enable power relay and three-phase bridge.

POSSIBLE TROUBLESHOOTING ISSUE

Find the cause of the block and then remove

it.
