Function Loss Response; P.013 Output Relay Configuration; Forward/Reverse Configuration - Reliance electric GV3000/SE Instruction Manual

P.026

Function Loss Response

Parameter Range: 0 = Generate a Fault trip (IET) and coast to rest
1 = Coast to Rest without a FAULT trip (IET)
Initial Setting: 0
Type: Tunable (at rest or during operation)
Refer to:

P.013 Output Relay Configuration

The user must provide an external, hardwired emergency stop circuit outside the controller circuitry.
This circuit must disable the system in case of improper operation. Uncontrolled machine operation
may result if this procedure is not followed. Failure to observe this precaution could result in bodily
injury. The controller is not equipped with a COAST-STOP push-button. The factory-installed jumper
at the Terminal strip must be removed, when FUNCTION LOSS input, COAST-STOP push-buttons,
or other interlocks are used to stop the controller.
Description: This parameter specifies how the drive will respond to an open circuit between
terminal strip inputs 16 and 20.

P.027

Forward/Reverse Configuration

Parameter Range: 0 = Forward or reverse enabled from the selected control source.
1 = Reverse disabled from the selected control source.
2 = The state of the forward/reverse input is latched when the motor is started.
Initial Setting: 0
Type: Tunable (at rest or during operation)
Refer to: P.011 Terminal Strip Analog Input Configure
Description: This parameter specifies how the motor responds to forward or reverse inputs from
any control source.
When P.027 is set to 0, the forward/reverse input allows forward or reverse rotation of the motor.
When P.027 is set to 1, reverse rotation of the motor is prohibited and the forward/reverse selection
from the front panel or serial port is set to forward. Note that reverse rotation is prohibited
regardless of the polarity of the speed reference input.
When P.027 is set to 2, the state of the forward/reverse input is latched when the motor is started
(RUNNING LED is on). Direction changes requested from any control source after the motor is
started are ignored. Note, however, that this selection will not inhibit a motor direction change due
to a change in the polarity of the speed reference input.
Note: Forward means clockwise rotation viewing motor drive end, with the following conditions:
European motor and U,V,W of the Inverter connected to U,V,W of the motor at Forward
mode and positive speed reference selected (Refer to P.008, P.011).
in V/Hz or SVC regulation, setting H.016 (Sync Mode Select) or U.031 (SVC Sync Direction) to any
value but 'F' may cause the motor to operate in the reverse direction briefly regardless of the setting
in P.027.

4 - GENERAL PARAMETERS, DESCRIPTION
The motor will coast to rest.
The function loss error code (FL) will be displayed.
The output relay will be asserted if P.013 is configured for IET output.
The IET fault must be reset (RESET key) before the drive can be re-started.
The motor will coast to rest.
The output relay will NOT be asserted.
The drive can be re-started with the START key after the cause of the fault has
been removed.
