DC Brake
A51 DC Brake Enable
Used to enable/disable DC injection braking
Settings: 00=Disabled
01=Enabled 00 to 01 Numeric
Value 00
A52 DC Brake Start Frequency
Sets the frequency at which the DC brake will become
active. 0.5 to 10.0 0.1 Hz 10.0
A53 DC Brake Wait Time
Sets the time the drive will wait after A52 [
DC BRAKE
START FREQUENCY ] before applying A54 [ DC HOLD
VOLTAGE ].
0.0 to 5.0 0.1 sec 0.0
A54 DC Hold Voltage
Sets the level of DC braking voltage in percent of A82
[
BASE VOLTAGE ].
0 to 100 1% of drive
rating 0
A55 DC Hold Time
The time that A54 [
DC HOLD VOLTAGE ] is applied to the
motor after A53 [ DC BRAKE WAITING TIME ] has expired.
0.0 to 60.0 0.1 sec 0.0
Operating Frequency Range
A61 Upper Frequency Limit
This is an upper frequency limit similar to A04 [
MAXIMUM
FREQUENCY ] except that it can be set lower than A03
[ BASE FREQUENCY ]. A value of 0.0 will disable this
parameter.
Output Frequency
0.5 to 360.0 0.1Hz 0.0
A62 Minimum Frequency
Lowest frequency the drive will output continuously.
Refer to diagram in A61 [
UPPER FREQUENCY LIMIT ].
0.0 to 360.0 0.1Hz 0.0
A63 Skip Frequency 1
Sets a frequency at which the drive will not output
continuously. 0.0 to 360.0 0.1Hz 0.0
A64 Skip Frequency Band 1
Sets the bandwidth around A63 [
SKIP FREQUENCY 1].
The bandwidth is 2x A64 [ SKIP FREQUENCY BAND 1] with
½ the band below and ½ the band above A63 [ SKIP
FREQUENCY 1].
0.0 to 10.0 0.1Hz 0.5
A65 Skip Frequency 2
Sets a frequency at which the drive will not output
continuously. 0.0 to 360.0 0.1Hz 0.0
