Par Parameter Name Minimum Maximum Default Units
P2-18 Relay 2 function 0 14 0 -
Setting Function Logic 1 when
0 Drive running The PACMotion VFD is enabled (Running).
1 Drive healthy No fault or trip condition exists on the drive.
2 At speed Output frequency matches the setpoint frequency.
3 Motor speed > 0 The motor runs above zero speed.
4 Motor speed >= limit The motor speed exceeds the adjustable limit.
5 Motor current >= limit The motor current exceeds the adjustable limit.
6 Motor torque >= limit The motor torque exceeds the adjustable limit.
7 Analog input 2 >= limit The signal applied to the Analog Input 2 exceeds the adjustable limit.
8 Hoist brake control Enables Hoist Mode. The Output relay may be used to control the
motor holding brake. Refer to your Emerson Sales Partner for further
information.
9 Reserved No Function.
10 Maintenance due The internally programmable maintenance timer has elapsed.
11 Drive ready to run 0 to 150% of drive rated power.
12 Drive tripped The drive is not tripped, the STO circuit is closed, the mains supply is
present and the hardware enable input present (Digital Input 1 unless
changed by the user).
13 STO status When both STO inputs are present and the drive is able to be operated.
14 PID error >= limit The PID Error (difference between setpoint and feedback) is greater than
or equal to the programmed limit.
Note When using settings 4 – 7 and 14, parameters P2-16 and P2-17 must be used together to control the
behaviour. The output will switch to Logic 1 when the selected signal exceeds the value programmed in
P2-16, and return to Logic 0 when the signal falls below the value programmed in P2-17.
P2-19 Relay 2 / AO2 upper limit P2-20 200.0 100.0 %
P2-20 Relay 2 / AO2 lower limit 0.0 P2-19 0.0 %
Used in conjunction with some settings of Parameters P2-13 & P2-18.
P2-21 Display scaling factor -30.000 30.000 0.000 -
P2-22 Display scaling source 0 3 0 -
P2-21 & P2-22 allow the user to program the PACMotion VFD to display an alternative output unit scaled from
an existing parameter, e.g. to display conveyer speed in metres per second based on the output frequency.
This function is disabled if P2-21 is set to 0.
If P2-21 is set >0, the variable selected in P2-22 is multiplied by the factor entered in P2-21, and displayed
whilst the drive is running, with a ‘c’ to indicate the customer scaled units.
P2-22 Options Scaled Value is
0 Motor Speed If P1-10 = 0, Output Frequency (Hz) x Scaling Factor
If P1-10 > 0, Motor RPM x Scaling Factor
1 Motor Current Motor Amps x Scaling Factor
2 Analog Input 2 Analog Input 2 % (P0-02) x Scaling Factor
3 P0-80 Value P0-80 Value x Scaling Factor
P2-23 Zero speed holding time 0.0 60.0 0.2 Seconds
Determines the time for which the drive output frequency is held at zero when stopping, before the drive
output is disabled.
P2-24 Effective switching frequency Drive Rating Dependent kHz
Effective power stage switching frequency. The range of settings available and factory default parameter
setting depend on the drive power and voltage rating. Higher frequencies reduce the audible ‘ringing’ noise
from the motor, and improve the output current waveform, at the expense of increased drive losses.
P2-25 Fast deceleration ramp time 0.00 240.0 0.00 Seconds
This parameter allows an alternative deceleration ramp down time to be programmed into the PACMotion
VFD, which can be selected by digital inputs (dependent on the setting of P1-13) or selected automatically in
the case of a mains power loss if P2-38 = 2.
When set to 0.0, the drive will coast to stop.
