d5-03: Speed Limit Selection
Determines how the speed limit is set.
Setting 1: Frequency Reference Input
The frequency reference value at the active reference source (digital operator, External reference 1 or External reference
2) will be used as speed limit. Note that in this case all settings for accel/decel times (C1-01 to C1-08) and S-curves
(C2-01 to C2-04) will apply for the speed limit.
Setting 2: Parameter d5-04
The speed limit is set by parameter d5-04.
n
d5-04: Speed Limit
Sets the speed limit during torque control if parameter d5-03 is set to 2.
Refer to Speed Limitation and Speed Limit Bias
n
d5-05: Speed Limit Bias
Applies a bias set as a percentage of the maximum output frequency to the speed limit value.
n
d5-06: Speed/Torque Control Switchover Time
Sets the delay time for switching between Speed Control and Torque Control.
n
d5-08: Unidirectional Speed Limit Bias
Selects how the speed limit bias is applied.
Setting 0: Disabled
The speed limit bias is applied in the speed limit direction and the opposite direction.
Setting 1: Enabled
The speed limit bias is applied in the opposite direction of the speed limit only.
