Par
P4-08 Minimum Torque Limit
Active only in Vector Speed or Vector Torque motor control modes (P4-01 = 0 or 1). Sets a minimum torque limit, whereby when the
Optidrive is enabled, it will always attempt to maintain this torque on the motor at all times whilst operating.
NOTE This parameter should be used with extreme care, as the drive output frequency will increase to
achieve the torque level, and may exceed the selected speed reference.
P4-09 Regenerative Torque Limit
Active only in Vector Speed or Vector Torque motor control modes (P4-01 = 0 or 1). Sets the maximum regenerating torque allowed by
the Optidrive.
P4-10 V/F Characteristic Adjustment Frequency
When operating in V/F mode (P4-01 = 2), this parameter in conjunction with P4-1 1 sets a frequency point at which the voltage set in
P4-1 1 is applied to the motor. Care must be taken to avoid overheating and damaging the motor when using this feature.
P4-11 V/F Characteristic Adjustment Voltage
Used in conjunction with parameter P4-10.

8.3. Parameter Group 5 – Communication Parameters
8.3.1. Overview
Optidrive P2 provides many methods to allow the user to connect to a variety of fieldbus networks. In addition, connection to options
such as external keypads, PC and Optistick are possible. Parameter Group 5 provides the parameters required to configure the
various fieldbus interfaces and connection points.
8.3.2. Connecting Invertek Drives Options
All Invertek Drives options which require communication with the drive, such as the Optiport and Optipad remote keypads and
Optistick connect to the Optidrive P2 using the built in RJ45 connection point. The pin connections on these options are already
8
matched, such that a simple pin to pin plug in cable can be used to connect these options without any special requirements.
For further information on connecting and using these optional items, refer to the specific option User guide.

All Optidrives feature electronic thermal overload protection for the connected motor, designed to protect
the motor against damage. An internal overload accumulator monitors the motor output current over time,
and will trip the drive if the usage exceeds the thermal limit. When P4-12 is disabled, removing the power
supply from the drive and re-applying will reset the value of the accumulator. When P4-12 is enabled, the
value is retained during power off.
U,V,W
Stand motor phase sequence. Typically, this provides clockwise rotation of the motor.
U,W,V
Reverse motor phase sequence. Typically this provides counter-clockwise rotation of the motor.
Trip
When the overload accumulator reaches the limit, the drive will trip on It.trp to prevent damage to the motor.
Current
When the overload accumulator reaches 90% of, the output current limit is internally reduced to 100%
Limit
of P1-08 in order to avoid an It.trp. The current limit will return to the setting in P4-07 when the overload
Reduction
accumulator reaches 10%.
In this mode, when the drive functions as a Master in Master-Slave Mode, the data broadcast on the drive
network is the Master Actual Speed and the Master Torque Reference. This mode is suitable for Master-
Slave applications which required speed following.
In this mode, when the drive functions as a Master in Master-Slave Mode, the data broadcast on the drive
network is the Master Speed Reference and the Master Actual Torque. This mode is suitable for Master-
Slave applications which required load sharing between multiple drives.
