Relay Output 1
Relay Output 1 is a freely programmable relay output on the drive. The Relay supports both Normally Open or Normally Closed configuration.
Relay | AC Supply | DC Supply |
|---|---|---|
Relay 1 | N/C = 5A/250VAC N/O = 6A/250VAC | N/C = 5A/30VDC N/O = 6A/30VDC |
The diagram below illustrates the available settings for Relay 1.
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P1-30 | Relay 1 Function Select | N/A | 11: Motor Contactor Control | 0 ... 20 | RW | Y | N/A | 1 | 2082h | 0 | 130 |
P1-35 | Relay 1 Threshold Upper Limit | % | 100.0% | 0.0 ... 200.0 % | RW | Y | 1 = 0.1% | 1 | 2087h | 0 | 135 |
P1-36 | Relay 1 Threshold Lower Limit | % | 0.0% | 0.0 ... 100.0 % | RW | Y | 1 = 0.1% | 1 | 2088h | 0 | 136 |
P1-37 | Digital/Relay Output Hysteresis Band | % | 0.3% | 0.0 ... 25.0 % | RW | Y | 1 = 0.1% | 1 | 2089h | 0 | 137 |
The settings of Relay 1 are listed below.
Setting | Status/Function Source | Conditions for Status |
|---|---|---|
0 | Drive Enabled (Running) | Logic 1 when Drive is enabled and output stage is on |
1 | Drive Healthy | Logic 1 when no Fault condition exists on the drive. (“InHibit” is not included as a fault) |
2 | Motor Below Minimum Speed | Logic 1 when motor speed is </=minimum output frequency (P8-02) or </= DC injection at stop speed (P9-15) |
3 | Motor at Target Speed | Logic 1 when the output frequency matches the setpoint speed |
4 | Motor Speed > 0 | Logic 1 when the motor runs above zero speed |
5 | Motor Speed ≥ Limit | Logic 1 when the motor speed exceeds the adjustable limit as per set in P1-35 and P1-36 |
6 | Motor Current ≥ Limit | Logic 1 when the motor current exceeds the adjustable limit as per set in P1-35 and P1-36 |
7 | Motor Torque ≥ Limit | Logic when the motor torque exceeds the adjustable limit as per set in P1-35 and P1-36 |
8 | STO Status | Logic 1 when both STO inputs are present, and the drive is able to be operated |
9 | Rescue Mode Active | Logic 1 when the drive is operating in Rescue Mode |
10 | 2nd Anip > limit | Logic 1 when the signal applied to terminal DI5 (Analog Input 2) exceeds the adjustable limit as per set in P1-35 and P1-36 |
NoteWhen using settings 5, 6, 7, 10, parameters P1-35 and P1-36 must be used together to control the behaviour. The output will switch to Logic 1 when the selected signal exceeds the value programmed in P1-35 and return to Logic 0 when the signal falls below the value in P1-36. | ||
11 | Motor Contactor control | Used to control the operation of a motor contactor. Logic 1 when motor contactor is closed by the drive. |
12 | Motor Shorting Contactor Control Contactor control | Used to control the operation of a motor shorting contactor. |
13 | Direction of Travel | Logic 1 when direction down, Logic 0 when stopped or direction up. (Fwd command given and speed is positive): Up direction means a forward command has been given and motor turns clockwise (Looking at the shaft) and motor speed is positive. |
14 | Service Indicator | Logic 1 when service time interval set in P11-17 has been met. |
15 | Brake Control | Logic 1 when Relay is closed (Motor Brake Released) |
16 | Door Zone | Logic 1 when motor speed equals (P10-02 Early Door Opening Speed Threshold). |
17 | Light Load direction | Logic 0 = Easiest direction is up. Logic 1 = Easiest direction is downwards. |
18 | Travel limit counter reached | Logic 1 when Travel Direction Change Counter limit P10-05 has been reached. |
19 | Set speed and actual speed > P1-42 | Logic 1 when the % difference (as set in Speed following error P1-42) is exceeded between set speed and the actual speed (estimated speed in open loop/encoder speed in closed loop-with encoder) |
20 | Alarm | Logic 1 when an alarm is active, e.g P3-07 has been set to 2. |
Used in conjunction with settings 5,6,7,10 of Parameter P1-30 (Relay 1 Source Selector)
The table below shows the settings of P1-30 and the parameter that P1-35/P1-36 look at for the % to change the state of the Relay.
Setting | Status/Function Setting | Parameter monitored for Relay State Change |
|---|---|---|
4 | Motor Speed > 0 | P0-15 Post-ramp Speed Controller Reference |
5 | Motor Speed ≥ Limit | P0-15 Post-ramp Speed Controller Reference |
6 | Motor Current ≥ Limit | P0-25 Motor Current |
7 | Motor Torque ≥ Limit | P0-28 Output Torque |
Used in conjunction with settings 5,6,7,10 of Parameter P1-30 (Relay 1 Source Selector) to set the lower threshold of Relay 1.
This parameter works in conjunction with P1-15, P1-22, P1-28, P1-30 = 2 or 3 to set a band around the Motor at Target Speed (e.g. P1-15 = 3) or Motor at Zero speed (e.g. P1-15 = 2). When the speed is within this band, the drive is considered to be at Target speed or Zero speed. This function is used to prevent “chatter” on the relay/Digital output if the operating speed coincides with the level at which the digital / relay output changes state. e.g. if P1-30 = 3, P8-01 = 50Hz and P1-36 = 5%, the relay contacts close above 2.5Hz.
