YASKAWA TM.iQp.02 iQpump Drive Programming Manual
Description
Sets the time length of DC injection braking at start in units of 1
second.
When b1-03 = 2 actual DC Injection time is calculated as follows: b2-
04 * 10 * Output Frequency / E1-04. When b1-03 = 0, this parameter
determines the amount of time DC Injection is applied to the motor at
the end of the decel ramp. This should be set to a minimum of 0.50
seconds when using HSB. This will activate DC injection during the
final portion of HSB and help ensure that the motor stops completely.
Motor Pre-heat current in% of Drive rated current. This is used to keep
the motor warm to prevent condensation and is used in conjunction
with a digital input (data = 60).
Speed Search
Enables/disables and selects the speed search function at start.
0: SpdsrchF Disable - Speed search at start is disabled (estimated speed
method is used at other times)
1: SpdsrchF Enable - Speed search is enabled (estimated speed
method)
2: SpdsrchI Disable - Speed search at start is disabled (current
detection method is used at other times)
3: SpdscrhI Enable - Speed search is enabled (current detection
method)
Estimated Speed Method: Actual motor speed and direction is
estimated, then the motor is ramped from that speed to the commanded
speed.
Current Detection Method: Current level is monitored while output
frequency is ramped down.
Used only when b3-01 = 3. Sets the speed search operation current as a
percentage of Drive rated current.
Used only when b3-01 = 3. Sets the deceleration time during speed
search.
Delays the speed search operation after a momentary power loss to
allow time for an external output contactor to re-energize.
0: Disabled
1: Enabled
Delay Timers
Used in conjunction with a multi-function digital input and a multi-
function digital output. This sets the amount of time between when the
digital input is closed, and the digital output is energized.
Used in conjunction with a multi-function digital input and a multi-
function digital output. This sets the amount of time the output stays
energized after the digital input is opened.
PI Control
This parameter enables / disables the closed loop (PI) controller.
0: Disabled
1: Enabled (commanded speed becomes PI setpoint)
3: Fref+PI
Sets the proportional gain of the PI controller.
Sets the integral time for the PI controller. A setting of zero disables
integral control.
Sets the maximum output possible from the integrator. Set as a% of
fmax.
Sets the maximum output possible from the entire PI controller. Set as
a% of fmax.
