Description
Determines how long communications must be lost before a fault is
annunciated. Works in conjunction with parameters H5-05 and H5-04.
Motor Overload
Enables or disables the motor thermal overload protection.
0: Disabled
1: Std Fan Cooled (Enabled)
2: Std Blower Cooled
3: Vector Motor
Determines how much time will elapse prior to a motor overload fault
(OL1), when motor amps exceed the value set in parameter E2-01 by
10%. Actual (OL1) trip time will vary depending on severity of
overload.
Operation selection when the motor temperature analog input
(H3-09 = E) exceeds the OH3 alarm level (1.17 V)
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
3: Alarm Only
Stopping method when the motor temperature analog input
(H3-09 = E) exceeds the OH4 level (2.34 V).
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
Delay Time applied to motor temperature analog input (H3-09 = E) for
filtering purposes.
PwrLoss Ridethru
Enables and disables the momentary power loss function.
0: Disabled - Drive trips on (UV1) fault when power is lost.
1: PwrL Ride Thru t - Drive will restart if power returns within the time
set in L2-02.*
2: CPU Power Active - Drive will restart if power returns prior to
internal power supply shut down.*
* In order for a restart to occur, the run command must be maintained
throughout the ride thru period.
Determines the power loss ride-thru time. This value is dependent on
the capacity of the Drive. Only effective when L2-01 = 1.
Used to allow the residual motor voltage to decay before the Drive
output turns back on. After a power loss, if L2-03 is greater than L2-02,
operation resumes after the time set in L2-03.
The time it takes the output voltage to return to the preset V/f pattern
after speed search (current detection mode) is complete.
Sets the Drive's DC Bus undervoltage trip level. If this is set lower than
the factory setting, additional AC input reactance or DC bus reactance
may be necessary.
Stall Prevention
0: Disabled (Motor accelerates at active acceleration, C1-01 or C1-03.
The motor may stall if load is too heavy or accel time is too short.)
1: General Purpose (When output current exceeds L3-02 level,
acceleration stops. It starts to accelerate at current value recovery.)
2: Intelligent (The active acceleration rate, C1-01 or C1-02, is ignored.
Acceleration is completed in the shortest amount of time w/o
exceeding the current value set in L3-02.
This function is enabled when L3-01 is "1" or "2". Drive rated current
is 100%. Decrease the set value if stalling occurs at factory setting.
