GFK-3111A PACMotion VFD AC Variable Speed Drive User Guide 59
Par Parameter Name Minimum Maximum Default Units
P2-26 Spin start 0 2 0 -
0 Disabled Spin Start is not active. This setting should be used for all applications
where the motor is always stationary before the drive is enabled.
1 Enabled When enabled, on start up the drive will attempt to determine if the
motor is already rotating, and will begin to control the motor from its
current speed. A short delay may be observed when starting motors
which are not turning.
2 Enabled on trip, brown
out, coast
Spin start is active only following the listed conditions, otherwise spin
start is disabled.
P2-27 Standby mode delay time 0.0 250.0 0.0 Seconds
This parameter denes the time period, whereby if the drive operates at the frequency / speed set in P3-14
(Standby speed threshold) for greater than the set time period, the PACMotion VFD output will be disabled,
and the display will show Standby. The function is disabled if P2-27 = 0.0.
P2-28 Slave mode speed scale control 0 3 0 -
Active in Keypad mode (P1-12 = 1 or 2) and Slave mode (P1-12=5) only. The keypad reference can be
multiplied by a preset scaling factor or adjusted using an analog trim or offset.
0 Disabled (No Scaling)
1 Master Speed * P2-29
2 (Master Speed * P2-29) + analog input 1
3 (Master Speed * P2-29) * analog input 1
P2-29 Slave mode speed scaling factor -500.0 500.0 100.0 %
Used in conjunction with P2-28.
P2-30 Analog input AI1 signal format See Below 0-10 Volt -
Setting Signal Format
0-10 volt 0 to 10 Volt Signal (Uni-polar)
10-0 volt 10 to 0 Volt Signal (Uni-polar)
-10-0 volt -10 to +10 Volt Signal (Bi-polar)
0-20 mA 0 to 20 mA Signal
4-20 ma, trip on loss 4 to 20 mA Signal, the PACMotion VFD will trip and show the fault code 4-20F if the
signal level falls below 3 mA
4-20 mA, pr, spd 1 on
loss
4 to 20 mA Signal, the PACMotion VFD will ramp to Preset Speed 8 (P2-08) if the
signal level falls below 3 mA
20-4 mA, trip on loss 20 to 4 mA Signal, the PACMotion VFD will trip and show the fault code 4-20F if the
signal level falls below 3 mA
20-4 mA, pr, spd 1 on
loss
20 to 4 mA Signal, the PACMotion VFD will ramp to Preset Speed 8 (P2-08) if the
signal level falls below 3 mA
P2-31 Analog input AI1 scaling 0.0 2000.0 100.0 %
Scales the analog input by this factor, e.g. if P2-30 is set for 0 – 10 V, and the scaling factor is set to 200.0%, a
5 volt input will result in the drive running at maximum speed (P1-01).
P2-32 Analog input AI1 offset -500.0 500.0 0.0 %
Sets an offset, as a percentage of the full scale range of the input, which is applied to the analog input signal.
P2-33 Analog input AI2 signal format See Below 0-10 Volt -
