Parameters
Par. Description Range Default Explanation
P2-14(h) User relay output control
high limit Speed : 0 ... 200 %
(200 % = max speed)
Torque : 0 ... 200 %
(200 % = rated torque)
PID feedback : 0 ... 200 %
(200 % = max 2nd analog input) 100 % User relay output closes (P2-15=0) when
selected value in P2-13 larger than this
limit.
Limit in P2-14 relates to speed if P2-13 = 4,
to motor torque if P2-13 = 5 or to the PID
feedback value (2nd analog input) if
P2-13 = 6.
P2-14(L) User relay output control
low limit 0 … P2-14(h) 100 % Digital output state back to logic 0 when
selected value in P2-13 less than or equal
to this limit. (P2-13 = 4,5 or 6)
P2-15 Relay output mode 0: Normally Open (NO) 0 (NO) The drive must be powered up for the relay
contacts to be closed.
1: Normally Closed (NC)
P2-16 Zero Speed holding time 0 …
60 s 0.2 s Determines the time for which the zero
speed is held on the output before disabling
the drive.
P2-17 Start mode select Edgr-r Close digital input 1 after
power up to start drive Auto-0 When set to Edge-r, if drive is powered up
with digital Input 1 closed (enabled), drive
will not run.
The switch (digital input 1) must be opened
and closed after power up or after a clear-
ing a trip for the drive to run.
When set to Auto-0, drive will run whenever
digital input 1 is closed (if not tripped).
Auto-1…5 makes 1…5 attempts to auto-
matically restart after a trip (20 s between
attempts in default).
Drive must be powered down to reset the
counter.
Auto-0 Drive runs whenever digi-
tal input 1 is closed
Auto-
1…5 As Auto-0, except 1..5
attempts to restart after a
trip
P2-18 Spin Start Enable
(V/f mode only) 0: Disable 0 When enabled, drive detects motor speed
and starts driving the motor from this speed
(the motor speed can be in both directions:
forward or reverse).
A short delay of approx. 1 s will result after
enabling the drive before speed is
detected.
This function only works when parameter
P4-01 = 2.
1: Enable
P2-19 Keypad restart mode 0: Minimum speed 1 If set to 0 or 2, drive will always start from
minimum speed.
If set to 1 or 3, drive ramps up to the oper-
ating speed prior to the last STOP com-
mand.
If set to 2 and 3, the status of digital input 1
controls drive to start or stop. The start and
stop button will not work in this case.
1: Previous speed
2: Min-speed (Auto-r)
3: Previous speed (Auto-r)
P2-20 Standby mode 0: Disable
1 … 60 s 0.0 s If P2-20 > 0, drive enters standby mode
(disables output) if minimum speed is main-
tained for the time specified in P2-20.
If P2-16 > 0, this function is disabled.
P2-21 Display scaling factor 0.000 ... 30.000 0.000 Disabled if set to zero.
The variable selected in P2-22 is multiplied
by this factor and displayed as a real-time
value on the drive, in addition to speed, cur-
rent and power.
P2-22 Display scaling source 0: 2nd analog input 0 Selects the variable to be scaled by the fac-
tor set in P2-21.
1: Motor speed
2: Motor torque
3: Motor current
