YASKAWA ELECTRIC SIEP C710606 44B YASKAWA AC Drive T1000V Technical Manual
Description
Selects the output phase loss detection.
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
Output phase loss is detected when operating with less than
5% of the drive rated current. Detection can mistakenly
occur if the motor is too small relative to the drive capacity
rating (this parameter should be disabled in such cases).
Selects the output ground fault detection.
0: Disabled
1: Enabled
Controls the heatsink cooling fan operation.
0: Fan On-Run Mode - Fan will operate only when the
drive is running and for L8-11 seconds after stop.
1: Fan always on - Cooling fan operates whenever the drive
is powered up.
This parameter sets the delay time for the cooling fan to
shut off after the run command is removed when L8-10 = 0.
Used to input the ambient temperature. This value adjusts
the drives oL2 detection level.
Sets the oL2 characteristics at output frequencies below 6
Hz.
0: No oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0
Hz.
Selects the software current limit function. Typically no
adjustment is required.
0: Disabled
1: Enabled
Selects the detection of unbalanced output currents caused
by faulty devices in the output circuit.
0: Disabled
1: Enabled
Selects the installation type:
0: Heatsink-Cooled Drive
1: Side-by-Side Mounting
2: NEMA Type 1 Drive
Provides protection to the IGBTs by reducing the carrier
frequency at low speeds.
0: Disabled
1: Enabled below 6 Hz
2: Enabled for the whole speed range
Sets the time for that the drive continues running with
reduced carrier frequency after the carrier reduction
condition has gone (see also L8-38).
A setting of 0.00 s disables the carrier frequency reduction
time.
Configures an alarm when the output current exceeds
150% of the drive rated current.
0: Alarm disabled.
1: Alarm enabled.
Allows the drive to automatically adjust the drive output
voltage.
0: Disabled
1: Enabled
Sets the STo detection level as a percentage of the motor
rated current. If set to zero, then the drive will
automatically calculate an appropriate detection level.
