When you use the drive keypad Set U4-08 [Heatsink Temperature] to show the drive heatsink temperature. Figure 1. U4-08 [Heatsink Temperature] (When the heatsink plate is 89 °C) When you use a Multi-function Analog Monitor Output When you use terminal AM, set the parameters as shown in Table 1. Table 1. MFAO Settings Parameter Name Setting H4-01 Terminal AM Analog Output Select 408 (U4-08) H4-02 Terminal AM Analog Output Gain 100.0% H4-03 Terminal AM Analog Output Bias 0.0% Figure 2. Heatsink Plate Temperature Output on MFAO Note: The accuracy is ±5 °C (41 °F) for heatsink plate temperatures between 50 °C to 100 °C (122 °F to 212 °F). The installation environment has an effect on the temperature.
